Step back in time to celebrate the New Year with CityBeat and the Know Theatre. Our seventh annual swinging speakeasy celebration is all flappers and fedoras, with enough back-room games, appetizers and giggle juice — aka martinis, sidecars and manhattans — to keep you doing the Charleston all night long. A special champagne toast at midnight rounds out the party. Tickets sell out every year, so don’t be sloe like your gin. A portion of proceeds benefits the Know Theatre.
