It has no actual Mafia ties that we're aware of, but Lannie's Clocktower Cabaret, run by the inimitable Lannie Garrett, could certainly pass for a speakeasy. It sits on the 16th Street Mall, looking like nothing more than an actual clock tower. But when you walk downstairs into the cabaret section of the building, it feels like you've stumbled right into the 1920s. The lavish adornments and hushed atmosphere, along with the mood-appropriate food and drink, make the Clocktower feel like a secret hideaway for the classy set. Although Lannie's often presents burlesque and variety shows, it's also hosted local musicians including The Raven and the Writing Desk, Chimney Choir and Dan Treanor's Afrosippi Band, as well as national artists such as Suzanne Vega. Cool and comfortable, the underground venue is truly a world away from the busy downtown streets above.
