I'm looking for a good, relatively inexpensive restaurant to hold a low-key birthday dinner for around 10-15 people. Is there anywhere that's not too cramped, where it wouldn't be a problem for people to come and go (i.e. the waitress won't freak out if people come late or more people show up than RSVP'ed)?
I'm relatively new to Manhattan (and even newer to Chowhound...first post!) so any suggestion would be a great help! Thanks!
