There's a new restaurant called Netflix Bites, which aims give fans a "screen-to-table" experience where they can try dishes and drinks crafted by chefs and mixologists featured on unscripted Netflix culinary shows.
This is ... a little weird, right? The splashy marketing expenditure behind Netflix Bites coincides with Hollywood's biggest labor fight in decades, and the timing and opulence of the promotional campaign couldn't be more surreal. This month, after contract negotiations between the actors' union and major studios including Netflix collapsed, actors joined writers on strike, forcing a pause on production of most scripted films and TV series. That reality provides a jarring contrast to the escapism of the Netflix Bites experience.

The experience starts outside, with diners queued up behind the velvet rope as if they're headed into an exclusive movie premiere or a buzzy nightclub.
Instead, people like Justin Bernal are waiting to enter Netflix Bites, the streaming service's pop-up restaurant in Los Angeles' Mid-City neighborhood.
Bernal booked a table two months in advance for a date night with his wife, to see some of their favorite Netflix shows come to life. "We watch Iron Chef, a lot of these other shows, Nailed It — great shows," he said.
That's the idea behind Netflix Bites, to give fans a "screen-to-table" experience where they can try dishes and drinks crafted by chefs and mixologists featured on unscripted Netflix culinary shows.
But sometimes, it's reality that bites.
About The WGA and SAG-AFTRA Strikes
The Writers Guild of America (WGA) and the Screen Actors Guild (SAG-AFTRA) have been negotiating for new contracts with Hollywood's studios, collectively known as the Alliance of Motion Picture and Television Producers.
The WGA went on strike May 2. It is the first WGA strike in 15 years; the last work stoppage began in November 2007 and lasted 100 days.
SAG-AFTRA went on strike July 13. It marked the first time Hollywood performers and writers have simultaneously walked off the job since 1960.

This month, after contract negotiations between the actors' union and major studios including Netflix collapsed, actors joined writers on strike, forcing a pause on production of most scripted films and TV series. That reality provides a jarring contrast to the escapism of the Netflix Bites experience.
It's not the company's first marketing event adapted from its streaming content. There's an annual Netflix Is A Joke comedy festival in Los Angeles and, previously, Stranger Things-themed pop-up stores in a handful of major U.S. cities.

But the thought of dining at a Netflix event while many of the company's own employees are fighting for better pay and protections has left fans like Bernal conflicted.
"I support the actors, I have a lot of friends that are in the unions, especially in SAG-AFTRA, and seeing what they're going through sucks," he said.
At the same time, he had already paid a $50 deposit for the reservation that he didn't think he could get back. That was before SAG-AFTRA, a union representing about 160,000 TV and film actors, joined the Writers Guild of America, who have been on strike since May.
"I feel terrible," he said. "It's just having money invested in something, when money is tight for me already — it's hard to make those choices."
Inside the flashy Netflix Bites bubble
Once inside, the immersiveness of the experience might make the contentious backdrop easy to forget for some. The temporary restaurant exists in its own bubble — outside of protests, password crackdowns and negative publicity.
The event space, which occupies the bar and courtyard of a hotel, looks like a theatrical set: Floor lamps flank dining booths; there's a barbeque pit and pizza oven; Netflix-branded pillows, walls and plates make for instant photo-ops.
The dinner menu includes dishes from a who's who of the celebrity chef firmament: Andrew Zimmern's grandmother's meatloaf, Ming Tsai's truffle and mushroom-stuffed "MingBings," and Rodney Scott's pulled whole hog.

On a recent visit, the restaurant's wait staff exuded the poise of actors (and in some cases, actually are — don't be surprised if you recognize a face or two); they were hired through Australian celebrity chef Curtis Stone's events company, which is running the operation.
As a diner, it's easy to feel like you are the star of this quasi-reality production, like food judges on a competitive cooking show.
That excitement ended for some once the food arrived. Ivan Kim had been looking forward to trying dishes from Michelin-starred French chef Dominique Crenn after seeing her on Chef's Table.
"Atmosphere is good, pretty fast service," he said. "But the quality is not good because the chef is not there."

Of the dishes he tried, Kim gave his highest rating to the kimchi-topped Lady Zaza pizza from Ann Kim. For dessert, Nadiya Hussain's light and layered honey cake was a hit, according to online reviewers on Yelp.
Since the restaurant launched at the end of June, many of the chefs featured on the menu have stopped in to tweak their recipes and greet fans. But Ann Klein, a general manager with Curtis Stone Events, says, "We're not trying to be a three-star Michelin restaurant."
"That's not what this is," she said. "You're doing a pop-up. It's a casual summer residence."
Netflix Bites may be casual, but it isn't cheap. With appetizers priced as high as $65 (Curtis Stone's crab legs in curry), there's a distinct feeling of exclusivity. As you dig into the almost-too-rich "Millionaire's Shortbread," you might wonder whether Netflix executives will see any profits from this culinary production.

Let them eat cake, while actors and writers seek better pay
The extravagant salaries paid to streaming service CEOs have been a central point of contention in the strikes, in which actors and writers are demanding better wages, increased residual payments and protections from the use of artificial intelligence.
A Netflix spokesperson told NPR that this pop-up, as with the others, is a marketing initiative that's not intended to turn a profit.
Netflix spent about 8% of its roughly $32 billion revenue on marketing events in 2022, a slight decrease in its marketing expenses from the previous year, according to data from Statista. That's a relatively small sum compared to traditional major studios.

Striking writers have been able to pierce the restaurant's bubble, if only temporarily. On Netflix Bites' opening night, striking WGA members picketed in front with a pop-up of their own, within feet of diners lined up to go in.
"Instead of negotiating with us, Netflix decided to open an overpriced restaurant," wrote Adam Conover, a comedy writer and TV host who helped organize the picket line at Netflix Bites, which is just a block away from the WGA building.
Actor Adam Lustick played a fictitious BBQ chef of "CEO Fridays," serving "exclusively billionaires and media CEOs," he quipped during the improvised parody. Picketers returned again in July to pass out leaflets.
The bill arrives in a red-and-white envelope — soon to be a relic of the days when Netflix customers rented movies delivered by mail. The streaming giant is ending its once-revolutionary DVD-by-mail service in September.

Netflix and its temporary restaurant, meanwhile, aren't ruffled. Asked about the criticism it's received about the timing of the pop-up during the strikes, Netflix declined to comment. Klein, the restaurant manager, says the strike has not affected staff turnover.
After months of weathering inflation and a subscriber slump, Netflix reported steady growth in its most recent quarterly earnings. The pop-up, which runs into fall with no official end date, currently shows only a handful of open tables for the next 30 days. More reservations will open up on a rolling basis.
"We've been sold out, and have a waitlist anywhere from 300 to 500 every day," Klein said.

A federal judge has denied an unprecedented, emergency request by the Department of Justice to segregate thousands of California ballots in the midterm elections.
What the court said: In his 26-page ruling issued this evening, U.S. District Judge David Carter, a Clinton appointee, denied the Justice Department's request for a temporary restraining order to stop processing the ballots in question. "Never before in American history has the federal government, on the eve of an election, sought to coerce a state and local government to abandon their own Constitutional elections procedures and bend to the will of the Executive Branch," he wrote. Carter also expressed concern about taking action that could disenfranchise eligible voters and create chaos.
The backstory: The Justice Department wants California election officials to stop processing ballots pertaining to 20,000 individuals that federal officials say are "likely" noncitizens. State and local officials in California have countered that the DOJ’s list of “likely” noncitizens is unreliable, with a preliminary analysis by Los Angeles County showing that many on the list do not have active voter registrations.
What's next: The judge said that the federal government can address the issue by continuing to indict people for the crime of illegally voting as noncitizens. DOJ officials say in the last two months they have charged dozens of people for registering or voting without being a U.S. citizen.

State and local officials in California have countered that the DOJ's list of "likely" noncitizens is unreliable, with a preliminary analysis by Los Angeles County showing that many on the list do not have active voter registrations. The officials also claim that setting aside ballots just days before Election Day, when voting and processing mailed ballots are already underway, would be unlawful and infeasible and would disenfranchise eligible voters.
In his 26-page ruling issued Wednesday evening, U.S. District Judge David Carter, a Clinton appointee, denied the Justice Department's request for a temporary restraining order to stop processing the ballots in question.
"Never before in American history has the federal government, on the eve of an election, sought to coerce a state and local government to abandon their own Constitutional elections procedures and bend to the will of the Executive Branch," he wrote.
Carter also expressed concern about taking action that could disenfranchise eligible voters and create chaos.
"Once a vote is segregated, lasting harm has occurred," Carter wrote at the conclusion of his order. "If the Executive can discount votes and threaten an ongoing election due to unproven allegations, then our democracy is in danger. This Court declines to be a party to such process."
The judge said that the federal government can address the issue by continuing to indict people for the crime of illegally voting as noncitizens. DOJ officials say in the last two months they have charged dozens of people for registering or voting without being a U.S. citizen.
The DOJ's lawsuit in California, which was filed Oct. 15, is among a flurry of unprecedented actions the department has waged in states close to Election Day, raising alarms about federal interference in state election procedures.
Like in California, on Monday federal prosecutors asked Washington state election officials to review a list of 400 registered voters the DOJ believes are likely noncitizens. And last week, the DOJ filed an unusual lawsuit in Alaska that seeks to stop the state from certifying the results in its Senate race if the Republican incumbent loses due to votes for a longshot candidate with a similar name who is accused of being a spoiler candidate.
In California's most recent motion to the court, state Attorney General Rob Bonta, a Democrat, asked the judge to take into account the circumstances of DOJ's demand. "This litigation is a precursor to further interference here in California," Bonta wrote. "The Court must not be drawn into this chilling degradation of democratic values and constitutional principles."
The Department of Justice is expected to appeal Carter's denial, and the matter could ultimately wind up before the U.S. Supreme Court.
The DOJ has argued the issue is urgent since ballots are already being processed. Once signatures are verified on returned mail ballot envelopes, the ballots are separated from their envelopes to retain voter confidentiality and it then becomes impossible to retrieve an ineligible ballot.
Federal prosecutors have argued that votes by noncitizens dilute the votes of U.S. citizens. Voting by noncitizens has been shown by audits and investigations to be extremely rare.
The accuracy of the DOJ's list of "likely" noncitizens is still an ongoing matter of dispute.
A Los Angeles County analysis of a small sample of people on the DOJ's list found that a significant portion had said in records they were born in the U.S. But U.S. Citizenship and Immigration Services senior official Nicolas Bartell contested that in recent court filings, writing that his office's review of those individuals found none were U.S.-born.
Bartell did acknowledge the review found four of those people "might have a claim to U.S. citizenship."
He also provided the court additional details about the federal government's methodology in creating the list in recent court filings.
But University of Delaware political scientist Kassra Oskooi, who has been tapped as an expert witness by voting rights groups who are intervening in the case, responded in his own declaration to the court that he believes USCIS's matching protocol "is likely to be unreliable."
Background: Last December, the CPUC awarded a grant to telecom company AVX Networks to install subsea fiber internet infrastructure between Orange County and the island.
Why it matters: Catalina Island is home to more than 4,000 residents, and it draws thousands of tourists each year, but the internet connection is often slow and unreliable. The lack of a reliable internet connection affects critical services on the island such as remote learning and emergency response.
The island is home to more than 4,000 residents, and it draws thousands of tourists each year. Its slow, unreliable internet connection affects everything from remote learning to emergency response.
Lance Ware is CEO of AVX Networks, the company awarded the grant from the CPUC in December 2025. He told LAist host Nereida Moreno that the island depends on a very limited wireless internet link.
“When the town is busy, for instance, a cruise ship comes … the internet just gets crippled along with all the telephone services,” Ware explained.
Months after AVX Networks was awarded the grant, CPUC staff accused the company in July 2026 of breaking federal spending rules, citing insufficient justification and documentation for invoices.
The proposed plan would build the fiber-optic network under the San Pedro Channel from two points on Catalina Island to landings near Huntington Beach. Those cables will then connect to the Middle Mile Broadband Network in Stanton.
Where do things stand today?
CPUC staff allege that AVX Networks violated several program requirements, according to records.
“Since the award, AVX Networks has not shown itself to have the requisite administrative, technical, and operational capacity to deliver on its project, and AVX Networks has failed to comply with the terms and conditions of its award,” the CPUC agenda item records state.
Ware said he “vehemently disagrees” with those statements.
“There are allegations on things in there that do not make sense to us in that we've had no due process or cure and correct period to address,” Ware said.
What’s next?
If the commission terminates the contract and pulls the funding, Ware said the project will be delayed, but not stopped.
“This is not curtains down for us,” Ware added. “It's gonna take longer, and we'll have to find some other way to finance it, but we certainly haven't given up.”

Topline:
By LAist’s count, over 30 cities in Los Angeles and Orange counties are asking residents to approve tax measures on Election Day this Tuesday.
Why now? Municipalities cite stagnant revenues that haven’t kept pace with the rising costs of insurance, maintenance and infrastructure projects, and employee pensions. As a result, big cities, suburbs and small towns alike are all facing multimillion-dollar budget deficits. So they are asking residents to open their wallets — or potentially see deep cuts to basic city services.
Read on ... to find out if possible hikes are coming your way.
Southern Californians are feeling squeezed by the rising costs of, well, everything. And now their local governments are asking for more money, too.
By LAist’s count, more than 30 cities or districts in Los Angeles and Orange counties are asking residents to approve tax measures on Election Day, Nov. 3, citing stagnant revenues that haven’t kept pace with the rising costs of insurance, maintenance and infrastructure projects, and employee pensions. Big cities, suburbs and small towns are all facing multimillion-dollar budget deficits and asking residents to open their wallets — or potentially see deep cuts to basic city services.
The list of local measures on ballots from Culver City to San Clemente includes sales taxes, hotel taxes, business taxes, parcel taxes and utility taxes. Some ballot measures would extend or increase existing taxes while others are brand-new.
Much of the answer to why so many tax measures are on the ballot lies in Proposition 13, which capped property taxes in 1978.
Before Prop. 13, cities and counties relied on property taxes for nearly all of their revenue. In the decades since, they’ve increasingly turned to other types of taxes. Hotel and utility taxes, for example, were essentially nonexistent before the mid-1970s, and sales taxes represented a small sliver of revenue. Even as these taxes have grown, they’ve struggled to replace property tax revenue.
How Proposition 13 reshaped local taxes
Before 1978, California municipalities could raise taxes without voter approval. But in addition to capping property taxes, Proposition 13 also changed the rules for other taxes. Section 4 of Proposition 13 states that any special taxes (which are taxes designated for a specific use) must be approved by two-thirds of voters. A later proposition passed in 1986 requires that general taxes be approved by a simple majority of voters. General taxes are general purpose funds that cities can allocate as they please.
The rules could change again this year with Proposition 43, which would raise the share of votes needed to pass local special tax measures proposed by citizens to two-thirds. Currently, citizen-led special tax initiatives only need to win a simple majority.
Despite what the Nov. 3 ballot might suggest, sales tax measures are actually becoming less common, according to Michael Coleman, author of the California Local Government Finance Almanac. “More and more governments have started to exhaust the capacity for that. There’s a limit in how much you can do both legally and in terms of the tolerance of voters,” Coleman said.
State law caps the maximum combined local and county sales tax rate, and many Southern California cities are already at or near that cap, Coleman said. And sales tax isn’t as reliable as it used to be, amid the broader retail downturn and shift to a service-based economy (most services aren’t taxable in California).
All of that means cities are increasingly turning to “ticky-tacky, peculiar taxes” to come up with revenue, according to Kirk Stark, a professor of tax law and policy at UCLA.
The “conventional tax instruments” — property, income and sales taxes — are all limited by state law, Stark said. “Local governments that are hoping to satisfy demand for any kind of public expenditure have to turn to other, less conventional sources of revenue.”
This year, cities are asking Southern Californians to say yes to a wide range of taxes. Below, we look at three examples in South Gate, Orange and Diamond Bar.
South Gate: A utility users tax
South Gate is asking voters to approve something less common: a utility users tax, or UUT for short. If Measure SG is approved, the 8% tax would be added to bills for utilities such as electricity, water, natural gas, cable and phone service. The tax would bring in an estimated $10.4 million per year.
The city is facing a potential fiscal emergency and a $9.4 million budget deficit. Earlier this year, South Gate began cutting back services, including eliminating its crossing guard program and assigning fewer police officers per shift.
At a City Council meeting on the tax measure earlier this year, several residents spoke against the measure, with some calling the deficit a result of potential financial mismanagement that shouldn’t be pushed onto residents. Others said the monthly costs would simply add a new burden to already tight budgets.
“Being a homeowner here for the past 13 years, I have seen my utilities go up as well as the cost of living, my insurance for my house, and my car insurance go up. I believe there’s got to be a way to fix this problem without the UUT measure,” one resident told the City Council.
“I’m extremely frustrated that you now want to do electricity, water, sewer, cable, cell phone, gas. ... That hurts us. You’re passing that on to us, and that is absolutely not acceptable,” said another.
Most people don’t book a hotel in their own city. That’s made hotel taxes an easier pill to swallow for voters, since the tax is mostly levied on visitors.
The city of Orange is asking voters to approve Measure J, which wouldraise the hotel tax from 10% to 14%. Orange is one of 10 cities across Los Angeles and Orange counties where voters will decide in November whether to increase or establish a local hotel tax, also known as a “transient occupancy tax.”
Orange residents will also vote on a 1-cent sales tax measure, as the city projects a $27.6 million deficit that it calls “one of the largest financial challenges in the city’s history.” The sales tax is expected to bring in $37 million annually, and the hotel tax would add $3 million.
Diamond Bar: A new 1-cent sales tax
Diamond Bar voters will decide on Measure Q, a 1% local sales tax that would add a penny per dollar to purchases of taxable items. The city estimates the tax will bring in an additional $6 million annually, which could help plug a projected budget deficit of $5 million a year by 2030.
“The city’s challenge is simple: costs for city services are going up faster than revenues,” states Diamond Bar’s fact sheet on the measure, which cites rising public safety costs and $100 million in infrastructure and maintenance needs.
Several other cities have local sales tax measures on the ballot, including Santa Ana’s 1.5% sales tax extension and Los Angeles’ sales tax increase for the Los Angeles Fire Department, Measure FD.
“There’s a variety because circumstances among these local governments vary. The types of economies among governments vary, the local conditions, even the preferences for what type of revenue measure or tax measure might work varies,” Coleman said. “A local government that’s looking at one of these is going to look at a number of different options and consider what might be most palatable to the voters in their community.”

At the height of the Los Angeles fires in 2025, millions of residents were exposed in a 24-hour period to toxic lead levels from smoke that were 80 times higher than the typical background level, according to a new study. Researchers from the California Institute of Technology compared the chemical composition of smoke from the Eaton Fire with that of a wildfire and found that the urban plume had more lead, arsenic and halogens (which include chlorine and bromine) linked to burning vehicles, building materials and electronics.
Why it matters: “The main, key finding is really that wildfire smoke is very different fundamentally from the urban smoke,” said Nga Lee “Sally” Ng, an author of the study published Wednesday in the journal Science Advances. With the new technology they used to measure what was in the smoke, they were able to “actually see the very detailed component of these particles that we are breathing.”
Health effects: Ed Avol, professor emeritus in the Keck School of Medicine at the University of Southern California who has researched the health effects of air pollution for decades, said significant exposure to heavy metals is consistent with what he’d expect, “but certainly surprising because we haven’t been able to document this sort of thing.” “One of the real advantages of this study is that it had the opportunity to make measurements sort of hour-by-hour across the sampling network. And typically we make measurements of airborne particulates and so forth a couple of times a week, at best,” said Avol, who wasn’t involved in the study.
The backstory: The two wind-whipped infernos in Altadena and the Pacific Palisades that ignited on Jan. 7, 2025, killed at least 31 people and destroyed more than 16,000 structures, mostly homes, and everything in them — cars, paint, furniture, chemicals under sinks and more. Millions of people were exposed to smoke, which across the entire United States has been linked to tens of thousands of deaths annually. A recent study found that metal mixtures in the leftover smoke, ash and debris from the deadly 2023 Maui wildfires were harmful to the lung health of people living nearby long after the burning ended.

With the new technology they used to measure what was in the smoke, they were able to “actually see the very detailed component of these particles that we are breathing.”
Co-author Haroula Baliaka said understanding the different chemical compositions of smoke from an urban versus a wildland fire helps bridge a missing gap in research. Wildfires are growing larger, more intense, faster-moving and more frequent largely because of drier and warmer weather associated with human-caused climate change. As urban growth and climate change push more fires into cities, researchers said monitoring and emergency response will have to adapt.

Thousands of structures burned, releasing toxic chemicals
The two wind-whipped infernos in Altadena and the Pacific Palisades that ignited on Jan. 7, 2025, killed at least 31 people and destroyed more than 16,000 structures, mostly homes, and everything in them — cars, paint, furniture, chemicals under sinks and more. Millions of people were exposed to smoke, which across the entire United States has been linked to tens of thousands of deaths annually. A recent study found that metal mixtures in the leftover smoke, ash and debris from the deadly 2023 Maui wildfires were harmful to the lung health of people living nearby long after the burning ended.
During the fires, researchers measured trace elements of fine particulate matter, or PM2.5, every hour reported by instruments in the Atmospheric Science and Chemistry mEasurement NeTwork ( ASCENT ), a relatively new network of air quality monitors across the U.S. that measures the size and chemical composition of these particulates in real time. Ng said ASCENT is the U.S.'s first measurement network able to measure the chemical composition of airborne particles in real time.
Researchers were able to see what chemicals were in the smoke, track how its composition changed over the fire’s course, and distinguish emissions coming from burning structures. From there, they estimated how many people across Los Angeles were exposed to the heavy metals, particularly lead, during the fire’s first days.
They compared the typical value of lead before the fires and the chemical makeup of smoke from a 2024 fire in Riverside County that burned mostly vegetation with data from the Eaton Fire plume. Contrasted with the wildfire smoke, the plume from the LA fire contained 50 times more lead, three times more arsenic, and seven times more halogens. At the peak of burning, about 7 million people were exposed for 24 hours to lead levels more than 80 times what’s typical.
Lead is a neurotoxin that can stunt children’s development, lower IQ scores and increase blood pressure in adults. Scientists still don’t know how short-term, high exposure to lead impacts human health. Arsenic exposure is associated with various cancers.
Yaguang Wei, assistant professor in the department of environmental medicine at Icahn School of Medicine at Mount Sinai who researches the health impacts of air pollution, wildfire smoke and severe weather, said their findings reinforced some conclusions of a recent study he co-authored that found, in part, that PM2.5 from wildfire smoke was more toxic than particulates from other sources.
“I think their findings are not surprising,” said Wei, who was not involved in the study. When fires burn properties, they’re also burning “a lot of lead on your wall paint and the plastics and electronics and those are very toxic” when they burn, he said.
Monitoring, policies and emergency response need to adapt, experts say
Wei said the study has “important policy implications.” He thinks governments should take stronger actions to protect public health during these fires by investing in more wildfire monitoring and public alerts, and having more prescribed fires.
For Avol, the study is a reminder of our “strange and increasingly dangerous new world” where urban and wildland intersect — and increasingly catch fire.
“It reminds us to be cautious and be concerned and, you know, think about what we can do to minimize this. We’re not going to stop using all these materials containing metals and halogens and so forth in our homes,” he said. “How do we protect people from being exposed to that?”
