With its 1,000-bottle library of spirits, its sleek interiors and elegant seating, the Widder Bar is certainly at the very top end of Zurich's establishments. For those who never have to count their change, they offer rare spirits for five-digit prices and exclusive single malts you might only taste once in your lifetime. Everyone else can just enjoy a nice, if not cheap, cocktail or glass of wine and take in the scenery - and the bi-weekly jazz concerts on Tuesday of course.
