There are a number of options to let loose this Halloween. Grab a costume, and check out these major parties (all dates Oct. 31 unless otherwise noted).

Ben’s Next Door Halloween Bash

If you haven’t had a chance to check out this new bar on U Street, here’s your opportunity. The owners of Next Door also own Ben’s Chili Bowl (it is literally next door). The Halloween event is complete with a costume contest. Details: bensnextdoor.com
