The entrance is a painting. Specifically, a gold-framed Amedeo Modigliani portrait hanging in Exchequer Pub on Wabash that appears cracked down the middle. Give it a gentle push and it opens into Club X.

The space has genuine Prohibition-era credentials. The building at 226 S Wabash once housed the 226 Club, a speakeasy-brothel that Al Capone controlled. Historians are confident he actually spent time there. Club X opened on December 5, which is the anniversary of Prohibition's repeal in 1933, a date the owners were clearly not subtle about choosing.

The cocktail program is where things get interesting. They do a wagyu fat-washed Old Fashioned, a banana-infused daiquiri, and a bourbon sour called "The Currant Situation" topped with a rosemary-citrus smoke bubble the size of a softball. The bartenders are attentive without hovering. For a bar inside a Loop pub behind a painted door, the whole thing comes together better than it probably should.
