Got here completely by accident. Didn't even know of this place until my friend dragged me in telling me the whole way how cheap and delicious the food here is.
He wasn't lying!:)
They have specials every day (like $1 tacos but these are not vegetarian) and their general food is extremely cheap in relation to the size of portions!
Half of the menu carriers dishes I don't recognize by the name but all looks like a delicious mix of beans/rice/sauces/tortillas in different proportions.
Note of caution: most of the food is pretty spicy and they don't really adjust it down even when they say they do.
Portions are better shared between two people (seriously).
You can also buy lots of stuff there as it used to be a little grocery store of Mexican specialties and they kept it (pickled cactus anyone?).
