Diner Reviews
  • "Food was great as always -- esp the steak salad and brussels sprouts. Service is consistently great. We live in CS so drive 40 minutes -- come repeatedly, often to meet friends from Denver. We come for the food -- not the "ambience.""

  • "We like to go for small plates. There is a lot of flavor packed into each one! Wednesdays, all wine bottles are half price."
    Dined on 8/20/2014
  • "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."

  • "Great food and great service. Wine Wednesday with half priced bottles is a great deal."
    Dined on 8/20/2014
  • "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."
    Dined on 8/19/2014
  • "We love it! Great food! Always something new and a lot of good old standbys. It's always kind of noisy, but the food and drink always overcomes it."
    Dined on 8/16/2014
  • "Good experience and we'll be coming back. The Wed night deal on wine is a real attraction and worth keeping up. The noise level in the main dining room is high but bearable. The bar scene looks attractive."
    Dined on 8/13/2014
  • "First time here in years and we had a delicious dinner and a very sweet waitress who offered wonderful suggestions. The italian egg rolls appetizer and the homemade coconut cream pie were fabulous! We will definitely be back!"
    Dined on 8/12/2014
  • "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?"
    Dined on 8/12/2014
  • "The food was outstanding. There was a nice variety of entrees to choose from - from seafood to the wild. Our guests were very impressed."
    Dined on 8/12/2014
  • "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."
    Dined on 8/8/2014
  • "We really like this restaurant and the food is always very good. It is just very, very noisy. We have taken to going mid-week and leaving the weekends alone because for us it is just too raucous in there."
    Dined on 8/8/2014
  • "Always a great time, mingling with friends over cocktails and apps!"
    Dined on 8/8/2014
  • "The food we had was bland with not much vibrant flavor or taste. I am not sure how all the dishes are but on our particular night it was not exciting."
    Dined on 8/5/2014
  • "I have been to this restaurant twice- once for a work dinner and once for lunch with my mom. Both times the food and service were incredible. The wine list is amazing!"
    Dined on 8/2/2014
  • "The food here is usually very good. The noise level is pretty high when crowded on the weekend nights. There beer list has deteriated to only a few choices from Boulevard. No good IPA OFFERING AT ALL!"
    Dined on 8/1/2014
  • "Food cocktails and service were fantastic. A little noisy but more "bustling" thank a bother."
    Dined on 8/1/2014
  • "Waited 10 minutes for host/hostess to even acknowledge us, to be seated for a 7:15 reservation. Server was super busy w too many tables. She did her best. Food was good w/ many interesting items on the menu. Food was served lukewarm. Noise level was very high. We will try again & sit outside & hope that the food is served Hot!"
    Dined on 7/31/2014
  • "The food is always outstanding! I try something new every time, but the beef tenderloin is my fall back. It melts in your mouth! The first bite confirms that the food is fresh. The garden outside is a dead giveaway. You will not be disappointed."
    Dined on 7/25/2014
  • "Five in our group for dinner. We had a pasta dish, a salad entree, the special and burgers. Also the chilled cucumber mint soup. All outstanding. Definitely recommend."

  • "I am not a Food Critic, but The Pork Chop was magnificent."
    Dined on 7/12/2014
  • "I ate for the first time Saturday night, the food was very good and the wait staff were very good. I've lived in castle rock for two years and just now decided to try your restaurant. I will recommend to all and will return for another night out. Thanks to all for making it a fun evening."
    Dined on 7/12/2014
  • "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."
    Dined on 7/12/2014
  • "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)."
    Dined on 7/10/2014
  • "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."
    Dined on 6/28/2014
  • "We went for the first time and everything was really good! I highly recommend the Idaho Nachos, and the peanut butter bites! Just hope they will bring back the brussel sprout, bacon, and corn risotto. We will definitely be back!"
    Dined on 6/28/2014
  • "We made reservations for the Bistro after checking the reviews online and totally agree with the recommendations. We both had the beef tenderloin and it was excellent! Fun martini list!! Great service!"
    Dined on 6/28/2014
  • "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!"
    Dined on 6/26/2014
  • "As always, service and food were wonderful! This is one of our favorite date night restaurants."
    Dined on 6/21/2014
  • "The service by far was better than the food, but the food was still good. I would recommend going here. Good salads and Tasty Desserts."
    Dined on 6/20/2014
  • "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!"
    Dined on 6/14/2014
  • "One of our favorite places to eat. Fresh and delicious foods. Don't think we have ever had a horrible dish as everything we have tried is delish! Was awesome they offer gluten free options. This place is a local gem and we will return."
    Dined on 6/13/2014
  • "This restaurant is a gem in Castle Rock. The food is wonderful and it is quiet enough for you to enjoy conversations with your loved ones. In addition, the grow many of the herbs and vegetables, making their salads the freshest around!"
    Dined on 6/3/2014
  • "I regret to say we will not be returning to the restaurant as the noise level is excessive, too much so to enjoy dinner. The restaurant has become a noisy bar scene, not suitable for dining."
    Dined on 5/23/2014
  • "Union has such an eclectic menu -- we love the variety! Lunch on 5/20 was excellent - the food was prepared perfectly and service is always top notch! We will be back! "

  • "Just love introducting new people to Union, love the small plates."

  • "We arrived early and thought we would have to wait, but we were seated immediately. Bar area was very noisy but we were seated in the other room and it was very pleasant. Saturday they have martini's for $5 all day. They are normally $11. My salad was very good. My husband had blackened tacos, and for him, they were too spicy. We would definitely come back and bring family and friends. Service was very good. Outside seating will be nice in the summer."
    Dined on 5/10/2014
  • "We went for a late lunch on a Saturday. Happy Hour drinks were excellent! Food was very good and the service was excellent. The server was friendly and well informed about the menu. Portions are large. We would go back."
