Food is pretty good here and so is the service. We come here often and never have to wait long to get seated. We enjoy the calamari, deviled eggs and the fish specials.

Great location, atmosphere and food. I enjoyed salmon, cauliflower mash, roasted Brussel sprouts. My cauliflower mash was cold and they promptly served me a hot portion. Michael provides us with excellent customer service.

The staff are always smiling (with eye contact!) when you come through the door! Wide menu options, fresh food -- lunch, dinner and brunch. Nice for a date, friends or family gathering. We enjoy the well planned design and bright atmosphere.
