Museum of the American Gangster

It may be small, but this newish museum is heavily steeped in both history and atmosphere. Located upstairs from a notorious former speakeasy, the two-room hideout is packed with curiosities like the bullet that killed Pretty Boy Floyd, a classic Tommy gun, and John Dillinger’s death masks. Be sure to take a guided tour to view the old speakeasy-turned-theater and be on the lookout for the restless ghosts of Lucky Luciano and other bygone mobsters who probably still haunt the place.
