Most disappointing aspect was the service. Waiter never returned to our table until it was time to remove plates. Our food was delivered by someone other than our waiter, who promptly left our table after dropping off the plates. Most disappointing was our waiters failure to return our table shortly after the plate were delivered to inquire as to whether the food was satisfactory and whether we needed anything else- -which we did. Alternatively we tried to get the attention of other waitstaff that were in view, but they were in consumed In conversation with other staff members near the bar. To make matters worse, when the check was presented the minimum tip on the automated payment device was 18%. I generally tip 20% for good service. But In this instance the required tipping amount seems to just encourage performance.

The service, food, and ambience was outstanding. Brought my family who was visiting from out of town. I’ve been numerous times for happy hour, but tonight we had the mushroom risotto, butternut squash ravioli, steak salad and steak flatbread. Legitimately want to go back again tomorrow and wouldn’t change a thing. Lovely experience. Thank you Union staff!

Last night was extremely busy due to the star lighting. Staff was going crazy, trying to accommodate everyone, resulting in service being delayed. The food is always terrific and we love going there. The music could be a little lower!

The menu is filled with great choices and the food and service is always excellent the only reason not to go back is because of the excessive NOISE level. It is extremely loud.

Cheesy to add money to the bill to give to "team" without asking my consent(Heart for Home or somethign like that.) Then saying they can take it off the bill "if I really wanted too." Classless. Service a bit off but understand that people are new. Food was worth going back for...

Service was on point. Food was delicious, a few items could have been seasoned better. Very accommodating to our needs. Drinks were fantastic! Food came out quickly and hot. Great spacing between tables and were able to get a table quickly. Liked that the bar area was separated out. They also have outdoor seating that is fully enclosed. Would absolutely go back and check out more of the martini menu and other food options!

If you have never had the Chop at Union, I'd highly recommend it! I'm not typically a pork chop person, but I'd order this again. This is what they are known for, and now I know why!

This place is incredible for the atomsphere, excellent service and creative drink menu. It has the ambience of a divey Colorado roadhouse, but thoroughly upscale food and service and very friendly attitudes of staff. My wife and I went for happy hour and ate/drank for $44! Best deal in castle rock!

This has to be one of the ten best restaurants in Colorado. The noise in the bar can get loud at times, but the dining room is fine. The level of service has always been outstanding and the menu selection is some of the best I’ve seen.

One of the BEST meals I’ve had out. The menu has something for everyone; I had the tenderloin salad LOVED IT! My sister had the salmon salad, ate every bite, my friend had the mahi-mahi sandwich and everything was just fabulous. We shared crème brûlée and the silk pie; oh my was it ever good! Our Server, Luz, was top notch. Can’t wait to go back!
