"I trace the origins of al pastor in Los Angeles back to Raul Martínez’s King Taco chain, founded in 1974, because Martínez installed some of the first trompos in the city to prepare Mexico City–style al pastor (pork marinated in adobo cooked on a vertical spit) and helped popularize the lonchera—serving tacos out of catering trucks—that became LA’s roving taco-truck culture." - Bill Esparza
