Glad we tried this restaurant but probably won't return. Food was good, but not great. Dirty Martini was returned because it was undrinkable (salty olive juice variation on vermouth was used), and replacement wasn't much better. Special martini for the night was good, but not special. We ordered flatbread for appetizer and received Tater Tot Nachos. We went with the... More

This Bistro was crowded for a Thursday night (or maybe that's the way it always is?) and the food was excellent. There are two rooms to this bar/ small restaurant. The atmosphere is no thrills, but the long table lit from the underside is a bit of the unusual. The food was outstanding. We split a fantastic tostada salad and... More

I enjoyed this place a lot! First they were very friendly and it had a great vibe. They have gluten free dishes, but are willing to do almost anything gluten free on request and the gluten free flat bread was EXCELLENT. Pricing as a little high but well worth the great taste and preparation and I look forward to eating... More

This is a local favorite, especially for lunch and happy hour. Great food with a lot of choices. Small plates are great, but enjoy the full meals as well.

This is a great place for lunch with girlfriends having lunch or drinks outside on the patio or lunch on a girls day. It is also great for any dinner or lunch. The atmosphere inside is also very impressive and the service is always great. I was recently there for lunch with my family last minute and we were accommodated... More

We celebrated a big birthday milestone here on Friday, which also happened to be St. Patty's Day. They did a great job serving us and making sure things were ok. The food was fabulous! They have a decent drink menu too! This might become a regular place for our family to eat at. My only complaint is that my parents... More

Never visited when it was a Mexican restaurant. This American Bistro is excellent. It's very busy and very important to have reservations. We luckily visited during restaurant week....and the choices and prices were very good. Both the salmon and the special surf and turf were delicious. Very attentive waiter was appreciated for frequent refills on water.

We've never had a bad meal at the Union Bistro. The food is consistently good, as well as the service. They definitely have the best happy hour in town! Do yourself a favor and save room for the coconut cream pie.
