We are not familiar with Castle Rock or its restaurants. We decided on Union Bistro because of the previous recommendations on TripAdvisor.

we were in downtown Castle Rock on a pretty day, stopped at Union for a mid afternoon lunch, very quiet, off hour which is a good time to eat there since they are crazy busy at dinner hour, even weeknights. lunch menu had interesting items, good service, will go back occasionally, prices mid range reasonable.

This restaurant is much better than it looks like it would be, just from the exterior appearance. I absolutely love the salmon with barbeque sauce , and the hamburgers and sandwiches are amazing ! My husband loves the turkey sandwich here and has ordered it multiple times. The beef flatbread pizza is very good, and has amazing layers of flavor.... More

Once we settled outside on the patio, we enjoyed a delicious meal. Our waitress was attentive and did not forget about us ( as can sometimes happen when one is seated outside.) Great beer list.
