Birthday dinner near the Metropolitan Museum for 7 people, Square Meal?

[MK440]

Hi all -- Been asked to find a dinner spot for about 7 people to celebrate a 30th birthday. We're doing a scavenger hunt in the Met and want a place for dinner that we can walk to from there. Looking for something under $40 per person, no sushi or Indian. Someone recommended Square Meal but they don't take reservations for more than 6, any other ideas?
