Solid, inexpensive, authentic-ish Mexican food. Love the little street tacos. Carne asada has a good flavor. Cabeza (head) and lengua (tongue) are also offered. They're both good, but the texture's a little strange. They also have a great little salsa bar and yummy horchata.
It was voted best Mexican in Tempe in the New Times I think. There isn't a lot of great competition, but I would agree that this is my favorite in Tempe.
**Edit** No more salsa bar. Just ask for them at the counter.
