This is an excellent mexican restaurant! It's clean and has a great ambiance. The food is excellent and the service superb. The only thing I didn't like was their thin house soup but the other people in our party liked it so it was probably just me. We signed up for their e-mail list and they have done a good job keeping in touch with us. Letting us know about entertainers that will be there and special brunches etc. Definitely worth trying!
Output:
4 stars
