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.

Thought the food was good, maybe expected a little bit better based on the description on the menu. Drinks were just ok, for the atmosphere, would have liked to have seen better quality alcohol in the drinks.

I love love love the happy hour menu and how it changes every season. They offer unique tasty small dishes. The current menu has an amazing goat cheese in spicy marinara sauce. You have to try it!

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!!!
