This restaurant is a wonderful place to meet front range friends. The menu includes creative small plates, traditional large plates, salads and more. My group sampled salads and small plates and found both to be delicious. The general restaurant seating area has space available for both large and small groups to gather. Floor to ceiling windows add an element of... More

So I ate here one time prior to this and was not crazy about what I ordered. This time I ordered the Salmon Salad & Crispy Broccoli. I can honestly say this is probably the best salad I have ever eaten. It was grilled salmon on arugula with apples, pecans & citrus Apple dressing with bacon broccoli saute. Simply incredible....

Recently went to Union for a girls night out and it was fantastic. The night we went they had 1/2 price bottles of wine. The appetizers were delicious and large enough for a meal. The entree as were beautiful and tasted even better. It was hard to decide what to get they have so many options for everyone. I have... More

I've lived in Castle Rock for 3 years and I was not too sure about this place, I had heard mixed reviews. Finally I went to lunch with a few friends and quickly realized I was missing out, the blackened fish tacos were amazing! My little one had chicken off the kids menu and she did not leave anything behind.... More

I hate to let out the secret as I want to keep this place from getting too crowed! Everything on the menu is superb! The atmosphere is delightful, and the service is excellent. Nothing bad to say other than the draft beer is limited but the martinis make up for it. You wont be disappointed.

I think I have had everything on the menu, including the martinis, and always was extremely satisfied with each. The quality, quantity, presentation and service are the best you will find anywhere. I have been with family, friends, business, romantic lunches and dinners. It is a place you can go anytime with anyone for any occassion.

Get there before 6pm on most weekdays and enjoy the wonderful appetizers (about half priced) and drink specials in the bar area. Always packed and with good reason. Great food and service.

We are not familiar with Castle Rock or its restaurants. We decided on Union Bistro because of the previous recommendations on TripAdvisor. Turns out it was a great lunch of duck confit, fish tacos and grilled Brussels sprouts. Based on food alone it would have been rated excellent but we had decided to have a beer and wine and the...
