Need a dinner spot for 20 folks, affordable, and preferably with a spot for drinks nearby

[m de p]

I'm hosting a reunion of Peace Corps volunteers in early February and we'll be dining out on a Saturday night. I live in Harlem and would love to find a spot up here, though we can also travel anywhere in Manhattan. I was thinking about Dinosaur BBQ but would love other recommendations. How about Florence's on 8th avenue? I've never been and I'm not sure if they could accommodate a group that large. Other suggestions? Any cuisine is fine, but affordable is a must and vegetarian options are a plus (not sure how many vegetarians we have in the group). TIA!
