I have been to this restaurant several times over the past year and decided that it was time to write a review. Here are my observations:
1. The food is great. I have had several items from the menu and never been disappointed with food quality.
2. The Concord location is cozy and clean (even the bathroom.) This place fills up quick because it is popular amongst locals.
3. Contrary to some of the other reviews that I read, I have never had any issues with customer service (with any person) at least not at the Concord location. In fact, during our last visit my wife and I joked and talked with the two girls working the register. They refilled our drinks without having to be asked to do so (which is one way that I gauge customer service at restaurants.
4. If you go there during the week and don't plan to eat in, call in your order and they will have it ready for you at their drive-thru.
