Annual Halloween Party at New Museum

This sinister museum may be one of NYC's best modern-art museums by day…but come Halloween, it's a bloodcurdling hellhole! (Well, kinda.) It throws a kick-ass party with prizes for the most creatively dressed and of course serve cocktails. You need to be a member to attend, but don't let that prospect scare you to death. Membership purchase is available at the door. Free with museum membership.
