The Green Mill dates to before Prohibition. Al Capone was a regular customer, and a secret escape tunnel under the bar reportedly still exists. The interior appears unchanged from the 1920s, making it an unusually atmospheric venue for live jazz. I also come for “The Paper Machete,” a variety show akin to a Berlin cabaret held Saturdays at 3 p.m. (arrive by 2:30 p.m. to secure seats).
4802 North Broadway. Tel. (773) 878-5552.
