Reasonably priced dinner for 10-12 people in Manhattan?

[almcg]

I'm looking for a great, low-key option for a festive dinner party for between 10-12 people that will cost about $40 per person. We are happy to just book a table or get a private room with a fixed menu. Any suggestions? Many thanks!

Is that "about $40" for food only? Preferred cuisines? Any avoids? Any particular neighborhood? Exactly when is this dinner taking place?
