There's sawdust on the floor and wooden barrels line the walls in this traditional proeflakaal (tasting room), which is a real find and a welcome escape from the Red Light District hinterland. De Drie Fleschjes is run by informed and relaxed bartenders who are only too pleased to pass on their secrets for sampling jenever (a gin-like liqueur) in wholesome, old-fashioned surroundings. Although one or two tourists may find their way in here, most of your fellow drinkers will be Dutch.
