Good dining experience always. Sometimes difficult to get in, but that’s common in goof restaurants. Save room for desert.

We went shopping at the Castle Rock Outlets then went to the Union Bistro for lunch. Perfect service and meal! I’ll request eating in the main dining room next time so we can watch chef cook.

This is a great restaurant to meet friends for happy hour and stay for dinner. The food is awesome, and the place is almost always busy. So reservations are usually required. The atmosphere is happy and buzzing. It's a bit on the expensive side, but...More

Had dinner 6 PM Thursday. Very busy, apparently quite popular. We sat at the "community table". Service was fine, prices in line. Restaurant is very noisy, loud. I found the menu to be limited, uninspiring. Not many vegetarian choices. Seemed heavy on meats. A veggie...More

Great location in Castle Rock Old Town but our lunch was nothing spectacular. The place was pretty empty as we were in late for lunch and just before happy hour. The server was very pleasant but my meal was poor - a simple BLT. I...More

Not necessarily but it can't hurt. It gets very crowded there. It is also a going out place in town. If the weather is nice you may want to sit out on the front porch. Have fun! Great food & place!!!
