Had heard about this place for years. I believe recently they expanded their restaurant into the shop beside them in the plaza.
Have to say the food was excellent but the ambiance left a little to be desired. Although I never visited before my understanding was it was very cozy. The new space while probably welcomed by regulars needs some work. The massively high strip mall tin ceiling was just a huge echo chamber which made everything loud. Lighting was harsh too. Not exactly sure why it felt that way, but very bright for a restaurant.
The food was the star here. Some of the freshest true Tex-Mex you could ever ask for so much better than the typical fast casual chain Tex-Mex.
Fix the ambiance and I could see this easily moving up to a 5 star place.
