The ambiance is Mexican street food all the way, from the informal atmosphere to the ice-filled reach-in cooler stocked with cerevezas and refrescos. But it's the corn tortillas, each one hand-pressed and griddled to order, that will draw you back again and again to this pint-size spot on NW 25th Street just west of the Museum of Graffiti. Whether they're wrapped around salty-sweet pork al pastor with pineapple, grassy nopal, or battered fish with cabbage and chipotle (all $3 apiece) the nutty, slightly sweet flavor of warm corn always comes through and delights. The secret here, however, is breakfast. In particular it's the carne asada and egg burrito ($8) or the veg version filled with sauteed cactus, beans, and the creamy, slightly salty cheese called panela ($8). Hangover? Check. Long day ahead? Check. You just can't? Double check. And to think, so much joy for ten bucks! It seems unbelievable, but here it's the real deal.
