North 6th Street, On the Right
Just past Buttonwood
Doesn't get much more authentic than this. Might well be driving through some small town in Mexico.
Tried a couple of tacos, complete with lime and radishes. One pork taco, one steak. They also have cow tongue. In season be sure to try elotes exquisitos - a Mexican speciality - corn coated with mayonnaise and rolled in grated cheese.
