1. Café Central
The sheer grandeur of Café Central makes it well worth queuing for. Established in 1876, this quintessential Kaffeehaus was a popular hangout among intellectuals in turn-of-the-century Vienna. Sigmund Freud, Leon Trotsky and architect Adolf Loos are all known to have taken coffee here. Order a Melange, a Viennese take on a cappuccino, choose a cake from the stand and laze the afternoon away under the pseudo-Gothic vaulted ceilings of the Palais Ferstel.
