I'm looking for a place for Xmas dinner. They'll be 15 people. Unfortunately, I need to stick to fairly traditional American/Euro. We can spend $100 pp (plus drinks,etc). Not too far from Gramercy Park would be ideal, but given the dearth of restaurants open on Xmas (except Chinese), anywhere in Manhattan would be OK. A private room would be fantastic, but probably too much to wish for. I looked at opentable but nothing jumped out at me. Thoughts?
