I'm planning a birthday party for early November and am looking for an affordable and fun but casual bar for my friends to gather at. I'm inviting about 30 people. I'd prefer a place where I don't have to make a reservation/rent out a room, but there will be a decent amount of space. And maybe some games to play? And at least a little food? I just moved way uptown from Park Slope and am wondering if there's a place that feels a bit like Union Hall somewhere in mid or upper manhattan. Any suggestions?
