Another great meal here. Service is fast and the food is tasty. Be warned that it is a bit loud and you need a reservation or you will be waiting a while. They are always packed.

We absolutely LOVE the fried broccoli and the peanut butter bites here. My mouth is watering as I type this! We've been here with friends just for fun, and for birthday celebrations. Everything we've had is fabulous!

My wife and I have gone here quite a few times for happy hour. Love the apps. Great Margheritas to wash down the apps. Friendly staff.

The restaurant has consistently good food, and good menu selections. The only draw back is that the table arrangement makes me feel crowded when we dine there.

Stopped in for happy hour. The food, drinks and service are excellent. We enjoyed the happy hour menu (Lime margaritas, calamari, spicy shrimp, & crab cakes) - our choices were excellent.

Have been here many times, always good selections and service. The salmon/arugula salad was delicious! Their appetizer courses are wonderful and varied. One of my favorite restaurants in Castle Rock.

Their martinis are to die for and the broccoli Sriracha is so good! Actually everything on their menu is delicious, especially desert. Union is my favorite restaurant in town for happy hour speciality drinks and tasty food!

First of all, make reservations which I did for 7 pm. Got there on time and was seated within 7 minutes but saw many people come and go due to no reservations. I read the reviews from here and got the Crunchy Broccoli with Siracha sauce small plate as an appetizer - amazing. Martinis are half price on Saturday so... More
