WINE. GRAPPA. AMARO. VERMOUTH. Babylon Sisters is a wine bar located in uptown Waterloo. We focus on female wine producers, and carry almost exclusively consignment wines. We also have a small collection of natural wines. Join us on the cozy main floor, the spacious upper level, at the bar, or in the front window corner. We prefer walk-ins, but will take reservations for groups of 6 or more.
