Founded in 1974, King Taco began its operation from a converted ice cream truck. On a summer night in 1974, Don Raúl and Doña Lupe stationed their taco truck next to an East LA bar where they became popularly known. Today, the Mexican fast-food favorite has since expanded to 22 popular locations. King Taco serves a wide variety of authentic Mexican foods, and has been recognized by prominent food critics. King Taco is one of the few surviving original Los Angeles restaurants.
