Halloween will be over and the world will have returned to semi-normalcy tomorrow, but D.C.'s KABIN (1337 Connecticut Ave. NWlounge wants you to retain the spirit for an extra day. Tomorrow night, the Dupont Circle lounge will transform its Alpine-inspired decor into a haunted house for its Heroes vs. Villains party

Costumes are strongly encouraged, because bottle service will be facilitated by people clad in superhero costumes. Don't be that one person who thinks they're "too cool" to dress up. For $20, you can purchase tickets to the open bar, which will be held from 11 p.m. until midnight. Consistent with the superhero theme, the open bar will feature specialty drinks like the Incredible Hulk.
