There have been a lot of posts about looking for venues to host fairly large private groups. I had to go through this recently, and thought I'd share the info I was able to gather.
I needed a private room for a lunch for 25-35 people. I wanted the food to be good, the decor to be nice, and service to be solid. Because of the preferences of some attendees, a Chinese banquet type wasn't an option.
We ended up considering Perbacco, Absinthe, Prospect, Town Hall, and One Market, and eventually chose One Market. I will reply to this post with information on each.
