El Potosino has been here for years; I'm surprised my review is the first! This is a pretty good little family-owned place; the food is more authentic than regular TexMex but it's way better quality than you'd find in a greasy taqueria. I forgot the name of the combo dinner I always get, but it has 2 cheese enchiladas and a cold plate with a taco, guacamole, and a queso tostada (I think it might be the Maria Special?) I always ask for onions on the enchiladas, and they don't mess around!
The service is great, but the seating is not very comfortable - in fact they need some new booths. The springs are shot in most of them and many of the seat covers are torn. I guess they don't want people chillin' very long. I usually prefer to get take-out for this reason.
Pros: Tasty, Attentive service
Cons: Uncomfortable seating, Limited parking
