We went here for lunch & had chosen it for the reviews, but we thought it was just Ok. It’s nothing special. The food is fine, the atmosphere is fine, but definitely not a four or five star.

We went for luncheon around 1PM on a Thursday. Still busy. So at that time as to be expected somewhat noisy when restaurant is full. Food was excellently well prepared and received in a timely manner. Professional staff.

Friendly staff and delicious food, plus martini specials on Saturdays! The truffle tots and mussels were especially good, as well as the fish tacos.

The food is good but the menu is limited. The atmosphere is fun and energetic. Good for a small or large gathering; nice to sit on the patio in warm weather.

Encouraged by the reviews, two of us stopped in for lunch about 1:30, and they were not busy. We each ordered the $25 Lobster Risotto after we asked the server how it was. She said it was very good. We were underwhelmed by the measly...More

Staff is great. Food is consistently wonderful. Bartenders are attentive. A lot of regulars but a very friendly place. Best restaurant in Castle Rock.

Not necessarily but it can't hurt. It gets very crowded there. It is also a going out place in town. If the weather is nice you may want to sit out on the front porch. Have fun! Great food & place!!!
