I am bringing a group of people up to New York from Washington, DC (day trip via bus)to see an exhibit at the Museum of the City of New york @ 1220 Fifth Ave @103rd Street. It will be most likely mid to late July on a Wednesday. I wanted to arrange a fabulous but not too expensive lunch for the trip preferably in an Art Deco setting. Any ideas? Otherwise I will consider Jean-Georges--(if they can accommodate)the food must be great at a good price and the setting elegant. I may have up to 50 people with me.
