I first ate here about a year ago and loved it. Now that I live in Phoenix I probably come here at least once a month or so. The service is generally good and the food is always amazing.
I've never actually had drinks for happy hour here, but they have some pretty good deals on food as well - guacamole, carne asada burritos, tacos among a few others are on their happy hour food menu. My favorite item on the menu is the cochinita torta - a pork sandwich - the bread is amazing.
I usually come with friends and we all love it (especially the guac).
