Awesome staff and service. Outside seating was great. Food is fresh and delicious. I wish they would open sooner so I can go there for breakfast. Definitely coming back.

Solid place! Ordered their chicken & ribs plate, and the ribs were fall-of-the bone tender. Chicken had a nice lemon flavor to it. Overall, good quality, great value, and you leave there feeling full. Haven't tried their breadsticks, but I hear they're great. I'll have to return back to try them next time I'm in the area.

Loved the service. everyone is friendly and helpful. Breadsticks are amazing, the pizza was just ok. The chicken and pasta was very tasty as well. We will def return but maybe not for pizza.
