El Vilsito is exactly what it appears: an auto-repair shop on Avenida Universidad. From around 7 pm onwards the cars are rolled out, plastic tables and chairs go down, and a trompo of marinated pork is set spinning on an open flame at the entrance. By 9 pm the place is rammed.
The al pastor is the reason — pork marinated with achiote and chilli, sliced thin from the spit straight onto a small corn tortilla, finished with pineapple, coriander, and onion. Each taco is 25–30 pesos, the salsas are punchy, and the al pastor itself is arguably the best in the city. Cash only, open until past midnight.
