15. Lincoln Hall in Chicago
Longtime Chicagoans know this castle-like 1912 building for its rooftop – where FBI snipers stood to make sure mobster John Dillinger didn't escape from the nearby Biograph Theatre. The crew from Schubas Tavern renovated this space in 2009, turning it into a two-level, 600-capacity live-music venue that Chicago-based agent Tom Windish calls "the Bowery Ballroom of the Midwest."
Fun Fact: The building used to house the 3 Penny Cinema -- Chicago’s first and only movie-theater with a liquor license.
