Cute restaurant towards the south end of downtown Castle Rock. They offer a great happy hour menu but you do need to sit in the bar area only to get the happy hour specials. They have a special happy hour menu and drink specials. I like that they change the menu from time to time. Its fun to try new... More

I have been to Union Bistro several times and have always enjoyed my meal. My other visits have been for dinner and I love their salmon with blackberry BBQ sauce. Since I recently stopped for lunch, I tried their sliced beef sandwich and did not really enjoy it. I expected the sandwich to just be sliced beef and cheese; however... More

Love this place! Great place for drinks and dinner with friends. I also enjoy going with just my husband. We eat here for lunch too. Martini's are delicious and they have many different flavors. Food is exceptional too!

Staff is great, fish sandwich to die for and you can't beat Martini Saturday!!! Great location in downtown Castle Rock. Lighting could sometimes be a bit better.

We stopped here on our way to Beaver Creek and we are so glad we did! Great ambiance, friendly staff and the food was fabulous! I recommend the blackened fish tacos and the chicken tostada salad. Would definitely be a regular here!

In downtown Castle Rock. The food was very good, even though the menu selection is a little small. Service was very efficient.

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....
