The Mancillas came to the United States 14 years ago from Mexico. Alberto Mancilla, 34, and his wife Irene Mancilla, 29, own the El Taco Loco Mexican food truck parked at San Pedro Drive and Central Avenue. They’ve operated their food truck in Albuquerque for the past five years. Their business is popular around the International District for its carne al pastor. This Central Mexico dish is meat marinated in a guajillo chile sauce and roasted on a spit called a trompo. Carne al pastor is distinct for being served with pineapple pieces in tacos, tortas or burritos. At El Taco Loco, customers don’t pay until they’re finished eating.
