This is one of the best Mexican restaurants in Madison. I've been there a couple times and enjoyed the food and atmosphere very much.
My first time there, I had the Frito Burrito. Fun to say and delicious to eat! The second time, I had smoked brisket taco platter. Both dishes were plentiful and yummy.
I also had the Frozen Flight of Margarita's. If you can't make a decision on which flavor to pick, this is a great way of getting mini Margarita's to try. They come in 6oz glasses and you get three flavors.
If you love Mexican food, get out to Tex Tubb's!
