Sunday Jazz Jam at Ginger's Revenge, on Sunday, October 25 at 2:30 PM. Put it on the calendar now so you don't miss it. The South Slope room pours around 17 taps for roughly 80 folks, which makes for a cozy hang when the acoustic sets roll through. Most shows run free entry, and the gluten-free ginger beer selection stands out if you're steering clear of the usual cider-only spots.
