My husband and I recently celebrated our wedding anniversary at this little gem. The manager and waitress were professional and very knowledgeable when it came to their menu and winelist. We shared the calamari which was tender and flavoursome and had the Truffle mushroom tortellini...More

This was another restaurant that has a good atmosphere, experience, service but the quality of the food is mediocre. Too bad. I think we may give it another chance in the future. Good front of house service.

As most know, you can get a discount by dining Monday to Wednesday. This past Monday was 30% off the food bill, but I must say it's worth the regular price. The service was efficient, knowledgeable and friendly. The risotto balls were very good, hot...More
