South side of Airport and Guadalupe in a sketchy looking fire extinguisher recyling shop. I won't say this is the best taco truck in town (commercial tortillas), but it's so good that to really distinguish the food these ladies serve up from El Rico and others, for example, would be pointless. it rivals the aforementioned for nicely seared pastor and carnitas tacos. This is the pastor that comes out as hot, seared crispy chunks of deeply "annato'd" red well seasoned meat and fat, not that stewed pork bull shit you get at lazy joints. The carnitas are the same, but shredded as they should be, crispy seared on the griddle, and nice and "porky" with little else to mess that up. My barber Lizzy recommended this place and I was blown away and embarrassed to have missed something for 5 years this good in my distant hood. 7 to 4 pm weekdays, 8 to 4 sat.
