Need help planning 40th Bday party for DH!!

Where can I have a party for DH's 40th Bday party?? I would prefer to have it in Manhattan....but I need some good ideas!! It's not until April, but I figured its never too early to start planning.
Any places you would recommend? I'm not looking for a sit down dinner.....it would just have to be a cool place with good drinks and dancing.
Thanks!
