With the 2014 release of his critically acclaimed film, "Chef," writer, director, actor Jon Favreau ("Iron Man," "The Wolf of Wall Street," "Swingers") tracks the journey of a fictional food truck and its quick-tempered chef on its rise from Miami obscurity peddling Cubano sandwiches to a place in the Los Angeles culinary pantheon.
If you think this is a quaint little movie about a minor trend, consider the group that showed up at its table.
A-listers who appear in the movie include Dustin Hoffman, Scarlett Johansson, Robert Downey Jr., John Leguizamo and Sofia Vergara. (As a softie supportive ex playing against hot-headed-temptress type, Vergara might be the most satisfying surprise ingredient in the film.)
Favreau, who wrote, directed and stars in the film as chef Carl Casper, drew inspiration from real life.
"The food truck scene has definitely become emblematic of Los Angeles," Favreau tells CNN.
"It mixes up Mexican, Korean, Jewish, health food ... every kind of culture here. It's a reflection of and a recombination of the foods and culture that make up the tapestry of L.A.
"I eat at as many food trucks as I can."
Roy Choi a must get
As soon as he finished his script for the film, Favreau says he sought out the consultation services of chef Roy Choi, the unrivaled boss of L.A.'s still-booming food truck scene.
In 2008, Choi created the now ubiquitous Korean barbecue taco and launched it from a truck he dubbed Kogi.
Today, Kogi operates four trucks that roam the city.
Imitators of Choi's famed Korean barbecue tacos (two crisp corn tortillas, caramelized Korean barbecue short rib meat, salsa roja, cilantro-onion-lime relish, Napa Romaine slaw, chili-soy vinaigrette) can now be found from New York to Hong Kong to Amsterdam.
Rather than being annoyed by the doppelgangers, Choi says he's honored.
"A lot of them (Korean-taco vendors) are putting their own spin on it," he says. "They don't call themselves Kogi, so it's a form of love."
"DJs all have the same music, the same beats to choose from, it's which ones you choose and how you mix them up that makes you an original," adds Favreau. "Food trucks are our bootleg tapes."
L.A.'s food trucks are an extension of Southern California's long-established "taco trucks."
These are typically plain white trucks that sell cheap and freshly made tacos, quesadillas and other Mexican "fast food."
Modern "food trucks" -- sometimes owner-operated (as in "Chef"), sometimes run by larger business entities -- have taken the mobile food concept and expanded the menu options considerably.
You can now buy everything from acai bowls to greasy burgers to Maine lobster from food trucks.
The shared lineage means the terms "taco truck" and "food truck" are sometimes used interchangeably -- but shouldn't be mistaken for the similar-in-appearance white "catering trucks" (known colloquially as "roach coaches") that pull up to construction sites, warehouses and office buildings selling pre-packaged sandwiches, bags of chips, candy and beverages to workers.
Apps track trucks
Food trucks travel the city and park at different places and times each day or week.
Of several apps that have been launched to help track their movements, Roaming Hunger
is among the most popular.
Many trucks operate their own websites to let fans know where they'll be on any given day and time.
Kogi, whose four trucks cover all of Los Angeles County, updates its site daily and covers various social media bases.
From the start, social media has been instrumental in the rise of food trucks.
Kogi was established in 2008, shortly after Twitter began to gain mass popularity.
Choi used Twitter to help build interest in his fledgling operation.
One of the most famous results was the day he parked his truck at midnight on the campus of UCLA during finals week.
When he arrived he found almost a thousand students lined up for his tacos.
"Twitter, that's why Kogi blew up," he says.
In "Chef," Favreau imitates the model, with the lead character's El Jefe food truck getting a huge boost from Twitter popularity.
Four-star parking lot
At L.A.'s The Brig parking lot (1515 Abbot Kinney Boulevard, Venice Beach), a food truck rally is held the first Friday night of each month, usually starting from 6 p.m.
More than a dozen trucks descend on the parking lot, selling everything from grilled cheese sandwiches to Spam musubi to cupcakes.
The parking lot, which Favreau calls "ground zero of the L.A. food truck movement," is where Choi first parked his Kogi truck in Los Angeles.
Show up for a First Friday event at The Brig and you'll see exactly how Hollywood food trucks have gone since then.
Through the crowd of eaters, a squad of valet parkers rushes out to park your car -- while you visit a parking lot.
Only in L.A.?
Possibly. But it's a critical darling that just may be coming soon to a parking lot near you.
