King Taco, a beloved Mexican fast-food chain, traces its roots back to 1974 when it first opened its doors in an ice cream truck. Don Raúl and Doña Lupe, the founders, quickly gained popularity by offering authentic Mexican cuisine next to an East LA bar. Over the years, King Taco has grown to 22 locations, serving a diverse menu that has garnered praise from notable food critics.

The iconic painting by Ricardo Barragan captures the essence of King Taco's humble beginnings, featuring the original marquee sign and the nostalgic 3rd street location. In the 1980s, this spot operated as an order-to-go establishment, where customers would line up at the windows to savor their tacos while perched on their car hoods. This unique blend of history and delicious food sets King Taco apart as a cherished piece of Los Angeles culinary heritage.
