Celebrity chef Will Goldfarb, who hails from the States and gained fame via Netflix's Chef's Table, runs what could be a nightclub but is in fact a dessert bar where patrons who book far enough in advance (you'll need to do so at least a month before your visit) can enjoy a decadent nine-course tasting menu matched with cocktails/mocktails/wine.
Those who wish to limit themselves to one dessert and a drink are relegated to the rear garden; bookings aren't always required for this option.
