Tremendous food that has only gotten better over time since the restaurant opened a few years back.
The tacos are the best item on the menu, and the quesadillas are a close second, in my opinion. This is not the typical Az-Mex quesadilla. It's deep fried and incredibly delicious. I'd go with anything including arrachera.
The salsa bar is as good as hyped here on Yelp. My personal favorites are the cilantro, the pecan, the peanut, and the strawberry (when they have it). A couple of great typical molcajete blends are there too.
Don't miss the house margarita. The happy hour price of a few bucks is a total steal. It's a ruby red grapefruit blend, and it's absolutely delicious (and well worth it even at the regular price).
You can eat like a king with a huge helping of food, great salsas, a quesadilla to split, have a margarita, and walk out for $15-20 per person including tip. Delicious food and one of the best places on Calle 16.
