Sunday Jazz Jam at Ginger's Revenge, on Sunday, November 8 at 2:30 PM. Put it on the calendar now so you don't miss it. The South Slope location runs about 17 taps and fits roughly 80 heads, making it the cozier of the two spots while the Riverside flagship anchors the operation. Both pour the same gluten-free ginger beer that put them on the map, and most shows roll in free with a casual acoustic setup that favors traditional sessions and impromptu sit-ins over amplified rock.
