    Union has a great menu with just a few main dish choices, but something for everyone and all done creatively. Be sure to try the chop and the peanut butter bite for dessert!

    Ate at the Union on a Friday evening and was promptly seated. Cassie the server was prompt and attentive. Broccoli appetizer was delicious with the side sauce. Salads were fresh and not overly dressed. Salmon was cooked perfectly and paired with yummy cheese potato side. My wife's chicken and risotto were flavorful. Finished with a peanut butter bite. The house cocktails come in their own shaker and are perfectly mixed. The Union has consistently great food and service!

    We're not foodies but we do like a tasty, healthy, well-portioned meal for a fair price with attentive service. That's what we got at Union Bistro. Our friends are moving to Castle Rock and we wanted a quiet place with good food where we could talk. At 1:30 on a snowy Wednesday, that's what we got with Union Bistro. Everything was good - not great or amazing - but good. Our experience met - and in some ways exceeded - our expectations. Try Union Bistro - I believe the same will be true for you.

    We have booked a table just to try the new place out. And we were very much surprised by everything from the great environment to food quality to the great service. We ordered appetizers and mains (salads) and after appetizers arrived we realized what a big mistake we have made ordering so much - the portions were huge. So we checked with the waitress and were able to cancel one of the mains, which was good for us. The waitress was very efficient, professional and friendly, provided great service.

    We decided to try The Union for a Friday night dinner. We made a reservation and were seated within 5 minutes of arriving even though the wait was 45 minutes. We ordered wine and after a small taste my wife decided she didn't care for it. Our waiter immediately recognized it and recommended a different one. She loved the replacement. The menu looked great so we ordered two small plates in addition to our main dishes. Big mistake. We loved the small plates (flatbreat and fried broccoli) and were fairly full by the time our main dishes arrived. Everything was delicious. I had the pork chops and my wife had the salmon. Would recommend both. It was a little noisy at times. Other than that it was perfect.

    A work colleague and I met for dinner at Union Bistro. The broccoli appetizer was delicious as was the steak flatbread. The recommended bottle of Rodney Strong wine was a great complement to our meal. The only down side to our experience is that we found the waitstaff to be brusque with us about completing our meal and leaving, even though there were no other patrons waiting for a table. Our conversation was interrupted several times by our server. I will try dinner there again for the great food and to see how the service is a second time.

    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 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.
