My future mother-in-law is throwing an engagement dinner in our honor for us to mingle and get acquainted with her friends (read: mostly people in their 60s & 70s) on a Sunday in November. We're looking for a spot with a private room for about 30 people that won't break the bank - about $50/person is the max. Would prefer Upper East Side but willing to venture further downtown. Any cuisine is fine. Any thoughts?
