We were celebrating the night we came here so I think we may have ordered half the menu and just kept eating and drinking wine. It was a great visit to Colorado and eating here was a highlight!

I was a regular at the Union years ago, but after a bad experience I never went back until just recently when friends encouraged me to try it again as management has changed and I was very pleased with the service and menu, our meal was great and I will return.

The food here is delicious! The food has a artisan flare. Happy hour is fun, but really busy! Have been there for lunch, which is more reasonable. Dinner with my daughter. a bit pricey, but it was a special occasion. She had the chicken. She really enjoyed it. Really enough to split or 2 meals! I had salmon which was... More

Good but average menu and food quality. The noise level is pretty incredible. If you find it hard to hear over a jet plane's roar, then pass on an evening meal here. Great wine prices on Wednesday though. Half price.

I didn't know I liked martinis until my friend introduced me. I love the martinis at the Union. A perfect Saturday consists of appetizers and martinis. We've eaten dinner several times there as well. The food is always good, and the service is great. It gets loud so sometimes difficult to hear conversation. None the less, a local favorite.

Stopped here one Sat for a HH dinner. Got to chatting with several friendly locals at the bar while I waited for a table and enjoyed the cheap drinks. We got a starter of calamari and it was delicious! Fresh, flavorful, fab. We also had mains--I had a salad, our youngster had a pulled pork sandwich that said it came... More

Food was amazing but our "30 minute wait" was almost 90 minutes. When we were finally seated, at one of SEVERAL tables that had been empty for quite awhile, the food came quickly and was good but I doubt I'll go back on a Friday or Saturday night again.

The Union (in their bar area) has the best Happy Hour in Castle Rock - the food is amazing and very inexpensive, and the house wine is also great! Mark is wonderful and many of the other people who work there are very friendly. It's an early Happy Hour (ends at 6:00) but it's worth getting there early if you... More

Ate once at happy hour. Had beef flatbread, calamari, and crab cakes. All were fantastic. The calamari was the best had in a while with lightly breaded large strips of fish. I also had the tap beer which had decent selection and my wife had excellent margaritas. This is a busy place so plan ahead. Fortunate the happy hour extends... More
