Tacos Envenenados El Minero

Tacos Envenenados El Minero, on Justo Sierra in the centro histórico, is one of the best-known spots in the city for tacos mineros, the folded, chile-dressed taco that historically fed silver miners working underground shifts. The name, which translates roughly to poisoned tacos, refers affectionately to the intensity of the house chile sauce rather than anything alarming, and regulars order the taco sencillo, one with bisteck, or one with bisteck and cheese depending on appetite. The counter is simple and functional - stools, a griddle in full view, and a fast-moving line during peak evening hours - with no pretension toward a sit-down restaurant experience. It opens only in the evening, running from 6PM into the early morning hours, catering to a late-night crowd as much as an early dinner one. No reservations are possible or needed; visitors simply queue at the counter and order directly.
