NYC Bday Venue

My friend and I want to throw our birthday party in NYC in February and we want to make this BIG. We want it at a nice classy lounge/club and invite tons of people. Any recommendations for a venue? Where would be the best place to have it?
A few of my friends have had parties and the club/promoter gave them free bottles for their birthday. Anyone know any contacts or how I can do this?
Thanks
