Staff is great. Food is consistently wonderful. Bartenders are attentive. A lot of regulars but a very friendly place. Best restaurant in Castle Rock.

Union has a great happy hour, great food and friendly staff. The Mac and cheese is awesome, the steak salad is my favorite.

Union is our standby — we’ve been here so many times, I long ago lost count. Martinis half price on Saturdays with so many kinds to choose from. Food is excellent too. The new patio is the bomb!

First visit to this restaurant in the "old town" section of Castle Rock, and they delivered on all counts. The small plates were wonderful, flavorful, and perfect for sharing. Crunchy Broccoli, Calamari, Polenta and fish tacos were our favorites...and each one was unique and well-prepared....More

This seems to be one of the only restaurants in the area that take reservations seriously. The table was ready when we arrived, service was prompt, and the food was great. No complaints at all.

Go back to Union Bistro even though it’s no a bit further away than when we lived in Castle Rock, they have the best peanut butter ice cream bites anywhere Nice atmosphere and very good small dishes

Union is a very consistent restaurant, with very nice food in all 4 times We've been there. Steaks are delicious, as well as seafood and sandwiches. Attending is also very nice although you may have to wait in a Saturday night. Highly recommended.

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!!!
