My fav hometown restaurant

Been to Union a hundred times and hands down the best food in Castle Rock. Great Happy Hour and Saturday night martinis as well. Wonderful local spot.

My husband and I wandered in here on a Saturday afternoon around 3. It turns out this was the exact right time to come, as their Happy Hour starts at 3 (goes through 6 I believe) and offers quite a few food and adult beverage options at reduced prices. Also, on Saturday their entire (extensive and wonderful) martini menu was... More

I love Union. Their food is unfailingly delicious. Ok--the service hadn't quite matches their food but it's not horrible, just a bit slow. Still, this is my favorite place to go for more of an up-scale dining here in Castle Rock. Their lunch is good too--excellent salads that will destroy any thoughts that salad-eating is a healthy choice. Just my... More

After discovering the Union Bistro last Summer, my wife and I have become regulars. The food, the service, and the friendly atmosphere make it a WINNER. Everything...and I mean EVERYTHING we have tried on their extensive menu has been tasty and wonderful. My only regret in writing this it that if enough people read it and try the place, we... More

I was expecting more from Union Bistro given the reviews here. I found the food to be regular to poor and the selection wasn't that creative. It is a pub setting--service was attentive.

The Martini's are yummy at Union Bistro and I love their flatbread pizza. Really, anything you eat at the Bistro will be delicious. Try the outside patio in the summer, a great place to spend have a few drinks with friends.

Great place for happy hours! But Friday nights especially, get there early as they fill up fast! Long table and some small ones are all they have and a small bar. But their food is wonderful, try the beef flat bread, awesome!

Found the restaurant on trip advisor and went based on reviews with our 2 kids. On Friday evening the place was packed but we only had to wait 15 min. Parking was a little difficult as we circled the block waiting for someone to leave. They have a large selection if good and everything is made from scratch. They also... More

Let me say right up front: this isn't world class food, but it is quite good food at a ridiculously reasonable price. The five star rating represents good food at great value. We've been here for lunch and happy hour. A total of seven people have ordered, and none has found anything they don't like yet. Here are some favorites... More

The food here is great and the service is pretty good. Nothing really stands out, although I wasn't disappointed either. Here's the kicker - I can't eat here because the wait time is ridiculous. Twice we arrived here on a Friday and/or Saturday night to 45+ minute wait for a table. I was able to stomach (excuse my pun) a... More
