I hate to let out the secret as I want to keep this place from getting too crowed! Everything on the menu is superb! The atmosphere is delightful, and the service is excellent. Nothing bad to say other than the draft beer is limited but the martinis make up for it. You wont be disappointed.

I think I have had everything on the menu, including the martinis, and always was extremely satisfied with each. The quality, quantity, presentation and service are the best you will find anywhere. I have been with family, friends, business, romantic lunches and dinners. It is a place you can go anytime with anyone for any occassion.

Get there before 6pm on most weekdays and enjoy the wonderful appetizers (about half priced) and drink specials in the bar area. Always packed and with good reason. Great food and service.

We are not familiar with Castle Rock or its restaurants. We decided on Union Bistro because of the previous recommendations on TripAdvisor. Turns out it was a great lunch of duck confit, fish tacos and grilled Brussels sprouts. Based on food alone it would have been rated excellent but we had decided to have a beer and wine and the...
