6. Museum of the American Gangster

Step back in time to the Roaring Twenties in this unique museum, the Museum of the American Gangster, located in a former speakeasy, where you can see two rusted safes which once contained enough money to buy the Lower East Side. This museum tells the story of organized crime in American from the slaver traders and smugglers in the time of the Founding Fathers all the way to the bootleggers of the prohibition era.
