Last month I was looking for a restaurant in the Union Square area to host a group dinner for my staff of 30 professionals. I couldn't find anywhere who would entertain a pre fixe less than $40 (and I was willing to do a Tuesday night at 5:30!) until I found City Tavern.
Ernesto, the owner and chef, was extremely accommodating. He put together a great menu on fairly last minute notice (one week!), was a pleasure to work with, and got us a great price point ($29 per person (not including alcohol).
We had the front 1/2 of the upstairs which essentially felt private for our team. Everyone thought the food, service, and atmosphere was excellent.
I definitely recommend the City Tavern for a group dinner.
Pros: Nice atmosphere, reasonably priced, good food
Cons: None noted
