Great tacos and a huge selection of tequila, I'm told they serve 200 different kinds. The first time I came, I had the tacos - very fairly priced and was stuffed quite generously. Don't expect to eat anything else though because this is all they serve for food. Also had a shot of tequila and it was good stuff! Super smooth.
My second visit was supposed to be drop in and take a shot kind of visit since we already had dinner elsewhere. Pro tip: do not just ask for a shot of tequila because as I said, they serve 200 kinds. Somehow I said surprise me because I didn't know which one I had last time (be careful because some of the good stuff cost upwards of $100 per shot)... And ended up with the reposado aka aged tequila, which cost $15 per shot. The bartender was great to talk to and I learned so much about tequila that night. Super friendly staff.
What I love about this place is they make it a big deal and gives everyone sombreros when you ask for a picture. It's campy but really cute.
