I have gone here a couple times now. We haven't had to wait either time we went. The tacos were fresh and their salsa bar was extensive. They have at least 5 different freshly made salsas out for you to try. They also have a huge hot sauce bar. I think that my favorite thing I have ordered there has been the corn. I asked for it to be "off the cob". It was cheesy and delicious. Their tacos are good, though, nothing to write home about.
The things that I didn't love however, was the fact that they only served beer, I was shocked at a Mexican joint (that serves alcohol) but no margaritas! The other thing that I didn't love was their guac and cheese dip. Their guac tasted as if it came straight from a bag from a wholesaler and their cheese dip was what not what I expect at a Mexican place, it was more like a spicy nacho sauce...
Overall, it was cheap, quick, and pretty tasty.
