Eat dinner here with a large party for a birthday day. Server was great however food was nothing to rave about. I order my meal off th gluten-free menu, which was the salmon dish, (all gluten-free). However this dish was not gluten-free. As I became sick. This restaurant really needs to understand the importance of gluten-free and make sure the... More

Was not impressed. Overpriced small portions. The valet parking is insane and unnecessary. One way in.

The sea scallops were just perfect as was the salmon dish. Since I mentioned it was our wedding anniversary, we were served two glasses of prosecco...on the house...very, very nice. We... More

Food was great! Service was slow and the waiter forgot us after he served. He did not offer dessert, we had to ask for the menu. The restaurant was not busy at the time we were there, he just was in a bad mood.

Everyone who works there including the bar staff, the wait staff, the assistant manager and the restaurants owner showed a caring attitude and made sure our experience in the restaurant was memorable. We ate at a leisurely pace: the waiter asked at several points if we were ready for the next course which puts... More
