The North Star Bartenders Guild threw a heckuva party — all for a cause. Public Functionary gallery in northeast Minneapolis was transformed into a late-night carnival, complete with a photo booth, fortune tellers, burlesque dancers, carnival games and plenty of craft cocktails by the city’s most notable bartenders. A portion of the night’s proceeds benefited the nonprofit Hold Your Horses, which provides equine therapy and adaptive riding services to adults and children with special needs.
