This is a GREAT place and these are good people! Service was awesome, the restaurant was very, very clean, and the food was fantastic. I'm a sucker for a good street taco with grilled chicken, and theirs is about the best I've ever had. VERY cold beer, too. We'll definitely be back.

Quesadilla with shrimp. I was pleasantly surprised. This is a steak Quesadilla served with 6 sauted shrimp. The whole thing is covered in queso blanco. It is served with rice and beans. I got this dish because it was the daily special. I paid a little over $12 with tax. The service was good. The place is cute. The building it is located in was a Subway in its past life. It is a cosy space. I enjoyed my experience there.

Starting off with, we loved the food and service, but I can't give a 5 star unless it's perfect. This was the 1st time I've seen a heel used for grilled cheese at any restaurant...BUT I applaud the no waste aspect. We will return and enjoyed our visit. My grande burrito with chicken was about what I expected and always something I recommend to others undecided. Wife got the taco salad with beef that did not disappoint!
