I was taken here by friends who live in the area and eat here a lot.The place was very busy, and had a good vibe to it.Lots of variety on the menu, the meals came out quickly and were big portions. Good food!

Union has become one of our favorite places for Happy Hour. There is a nice outdoor patio and delicious food options. The only reason I didn't give an excellent rating is that there was a nasty sewer smell near the front door. When we were...More

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!!!
