Architecturally impressive with its high vaulted ceilings in Palais Ferstel, historically significant, and highly sought after. Leo Trotsky, Peter Altenberg, Stefan Zweig, Adolf Loos – they all sat here, held salons, and made history. The cake selection is legendary, and the atmosphere is unique. However, those who do not arrive early or make a reservation often find themselves in endless queues with countless tourists – a sight that usually only elicits head-shaking from Viennese locals. Those who take the time will be rewarded.
