Union Bistro in Castle Rock

We were seated on time for our reservation. Service was excellent. The food was good. I would go back again. In fact, I have gone back to this restaurant four times.

We needed a late snack and drinks with friends. Union Bistro had several seating choices including a cozy patio. Appetizers were tasty and some unique. They have an extensive martini list. I was sad they closed at 10. I will be back for dinner.

You will find a lot of activity and action here along with a great selection of food and beverages. The outdoor dining is relaxing and a less hectic atmospheere. Enjoyed a great meal after a long drive.

1) the food is great. The menu changes seasonally. They have gluten-free options, and are ALWAYS willing to fulfill a customer's request. 2) Friendly, professional staff 3) the Happy Hour / Community Table & Bar are great places to run into friends, neighbors and meet new folks too. 4) contrary to another review...

Cattle country so limited options for those of us who don't eat meat. Probably worth a visit if you do.

The Union Bistro is very popular among the younger crowd, which we are not but still have a great time. They have a nice lite patio to use when the weather is good. It has been very busy during each of our visit and reservations are a good idea. However if you don't have reservation the wait is well worth... More

This is a diamond in the rough. The owners and the staff at the Union offer high-class menu options without the big city prices and parking headaches. Their menu changes often, yet they still keep the favorites (sometimes as a secret) for the regulars. Their drink specials along with the very long hightop and intimate booths make for an awesome...

My coworker and I decided to stop here while traveling back to DEN. The menu was full of many appealing items. We decided to order many of the little plates instead of full entrees. The tacos, broccoli, olives, and flat bread were all very good.

Best Martinis in Castle Rock. Offer distinct Happy Hour for Martinis on Saturday nights - how can you go wrong with that?

When you look at this place you would probably not think steak. But try their filet! It is absolutely incredible. Their meat is out of this world good. Also, make sure you get the Italian egg rolls. They are to die for.
