I am planning a birthday party for myself -- a milestone bday. And, want to have a party at a nice/swanky place with cocktails and lite bites (passed hor doeuvres or buffet) for about 70 people. I'm paying. Budget -$5-$6K. And, of course want be able to dance -- disco. I'm a 70/80s disco nut. Anyone have suggestions for a place or how to do this in nyc?
