Leo Würstelstand

Opened in 1928 and just a tram ride away from the city center, Leo is the oldest existing sausage shop in Vienna (beloved Austrian Chancellor, Bruno Kreisky, was among the fans). The bratwurst, nicely browned and crunchy on the edges, has yet to disappoint me, but the specialty of the house is the cheese-filled Käsekrainer. Mustard, kaiser roll, a can of beer on the side, and you have a deeply satisfying meal for five euros, whether at 1 p.m. or at 1 a.m. Also served: wine, snacks, cigarettes. Being outside the tourist zones means this is as Viennese an experience as it comes.
