Halloween night Mad Rose is having a Mad O Ween party starting at 8pm. Live music by DJ SAAM, who just played for a huge crowd at Echostage in DC this weekend. There will of course be costume contests, prizes and Halloween themed drink specials. There is no cover at the door, and the night will feature a special dance off with their "Thriller" Michael Jackson Tribute. The Halloween party is being thrown by Clarendon based Social DC PR and more info is on the Facebook event page.
