    OpenTable Diner Since 2009
    Dined on 8/27/2014
    Interesting menu emphasizing American cuisine with a twist. Pork chop was equal to its billing as a house speciality; other dishes tried were also very good. Good wine list. Polished and professional service staff knowledgeable about menu and wine list. Restaurant was quite busy with no empty tables so noise level was high but conversation at table still possible. Service was slow, so be prepared to sit and enjoy your evening.

    We called ahead for reservations and were accommodated promptly when we arrived. It was an anniversary and we asked for a quiet corner. Our table was on the patio and a very delightful experience. Menu is different and very well presented entres. Gina our server sensed our evenng and did not rush us, so we had a very leisurly enjoyable evening.

    We were received very well. Seated promptly. Surprised at no bread with meal or follow up on drinks. I asked for lemon in water and the lemon was added to my wife's tea. My steak was excellent, but the wife special (fish) was cold. Not a place to celebrate a special occasion. We were there for our Wedding Anniversary-Not a good choice on our part, but being new to Castle Rock, we are exploring all the restaurants here.

    I would liked to have had my dinner outside but the only tables seem to be for 2 people. We had 4 in our party and were offered the "red table", but this would have been too large for a nice evening of conversation for 2 couples. Could you reorganize the patio? I will be inquiring further about a group gathering of about 75 people. Can you help me out with this?

    This place was good, but not great. Prices reasonable & service very attentive. The main dining room is very loud, so if you want to enjoy your company, grab a patio seat. We started with the fondue plate. The cheese was barely warm, but it was fine for an app. The food was a little over cooked, but still very tasty. My wife got the filet & what should have been med rare, ended up being med well. However, the flavor and juicyness was still there, so no need to risk the send back. I got a couple of small plates which were ok. The beef flat bread is very tasty & very messy. The fish tacos were not very good. The fish was way over cooked and rubbery. I would not try again. Overall, we had a decent experience & will likely be back here again.

    The Chef and Management are trying hard inspite of their staff. The wine list was explorative but you can tell by most of the F&B pricing, what they want their beverage cost(a) to be. The dining room and patio are close to inaudible for conversational dining; and the table placement, size and lack of spacial breaks in the dining room give it a cafeteria edge. I would go back for Happy Hour and sit at the bar, but otherwise the service was slow-in existence, non-leading, and non-intuitive. The appetizers were good but unoriginal, the filet was cook perfectly but mid-quality, and the salmon was obviously farm raised and more than a couple of days old. However, the banana cream pie was the best I've had on the front range.

    Some friends and I went to their Happy Hour after work. A word of caution - you can't make reservations for the tables that offer Happy Hour - fortunately we were still about to get a spot. The small plates are awesome - crunchy broccoli, potato skin nachos, white cheddar fondue - for a group that is okay with sharing food, it was great and pretty cheap with the half price Happy Hour going on.

    Service is excellent and have given it a poor rating for one reason only: I have constantly asked management for wait staff to wear name tags -- we are regulars and are embarrassed when we cannot remember names of people who have served us before, and they remember ours! (We are of that age!) That is inconsiderate to their clientele and is a poor mark against the wait staff who are excellent, always rating 5 stars vs. management's 0 on this subject (otherwise management would get 5, too).

    2 best things: small plates and patio. Least best: noise level inside restaurant. Ordered several small plates, next time will order more. Variety of choices, broccoli was fantastic! Several had sandwiches, tasty and substantial. Patio a lifesaver for our family of 5 who wanted to have a conversation; too noisy and crowded inside. Maitre D very helpful! Would definitely go again.

    Our waitress, Mary Jo was awesome! She allowed us plenty of time to talk, but yet came back at all the right times. We only had appetizers, so I can't read the overall food quality. The calamari was cooked to perfection, not greasy, and tasty. It was too salty for my taste however. The Beef flat bread was incredible although topped with too much arugula. The place was a bit loud and parents were letting their children run all around the restaurant. I would definitely return to try more of the food because they all look incredible as they were passing by our table! If you want really great service ask for MJ or Mary Jo she was absolutely awesome!

    My husband and I had dinner on Saturday night and yet again were amazed by the consistent quality of the food. We have been here many times over the past 8 years and have never been disappointed. The food is always surprisingly creative and tasty and I think very fairly priced for what you get. I love that you can get an outstanding meal in a casual atmosphere and the wait staff is always ready to assist. Try the double chocolate bread pudding with sea salt caramel ice cream - yum!
