In 2008, Roy Choi, a classically trained chef who once worked at the Beverly Hilton in Los Angeles, took his Korean-Mexican fusion food to the streets. There, his beef short rib taco with a special, 21-ingredient sauce quickly emerged as his signature dish. From one truck, which Newsweekdeclared “America’s first viral eatery,” Kogi has expanded into an empire, with five trucks, whose locations on any given day are tweeted to over 96,000 followers, and four brick-and-mortar establishments. Many, including Smithsonian magazine’s very own food columnist Jonathan Gold, feel like food truck culture is indebted to Kogi, which proved that delivering “high-end food at street level prices,” as its website says, is possible. – Megan Gambino
