They have enormous burritos with tons of fresh toppings. The salsa, guacamole, and Texas caviar are especially good. I usually get the kids' "mini mojo," which comes with chips and salsa, and it's plenty of food. They also have $1 tacos on Saturdays (the steak tacos may be a few cents more). The atmosphere is quirky, with lots of local art around.
We usually eat at the Dayton Blvd location.
