I wanted to pipe in and give a more favorable review of this place. I have loved going here for years! I will agree that it is not for the authentic Mexican experience - but because they have a good variety of tasty food and drinks.
I usually go to the Robinson location as it's near my office. It's a lot more spacious than the Oakland location, which can feel a bit claustrophobic to me on a busy night. (Though late nights there are fun with half-off food specials after 11...)
I like getting the chips with different dips. The Yucatan Bean Dip is to die for, and the Dos Equis queso dip and fire-roasted tomato chipotle salsa are also great. For entrees I usually go with the fish tacos or one of the quesadillas.
They have great lunch specials too. I can get a huge quesadilla and a salad with their delicious lime-cilantro dressing for like $7! Good Happy Hour specials, too, on margaritas and drafts.
Authenticity aside, I've been here a million times and I know I will be here a million more.
