Explanation : One way to find a speakeasy during Prohibition was to search for a green door. Thanks to strict rules, there weren’t many other ways to advertise to would-be customers. One of Chicago’s most historic speakeasies is still in operation today: the Green Door Tavern, which opened in 1921 and still proudly celebrates its Prohibition roots.
