They have an entire gluten free menu which was a surprise and was very helpful. The service from our waitress was excellent, warm and kind. It was a nice place even on a busy Sunday, no annoying music playing like other restaurants!

As someone who’s allergic to gluten, I thought subs were never a thing I could enjoy again. Until now! What a treat. Fantastic gluten free bread. My Cubano was out of this world. Thanks, guys!

I've eaten here many times and each time the food is absolutely fabulous. They also have gluten-free options. And I must say, their gluten-free options are the best I have ever had. Service is always good here. The Place is always clean and there is many seating options for small and large groups. Bathrooms are big and handicap accessible. You do pay for what you get so don't expect it to be too cheap but it is not over the top expensive.

Beautiful casual restaurant. Live music with a guitar player singing folk songs I knew. Waiter said this dish was new, so of course I ordered it. Grilled chicken breast on a bed of fluffy rice and a mild creamy sauce. Brussels sprouts were crispy with a delicious, slightly sweet basalmic drizzle. I could have eaten a pound of those. Gluten-Free. Highly recommend!
