With its hexagonal skylight, allegorical sculptures and beautifully lit arcades in Italian Renaissance style, Palais Ferstel hearkens back to a more glamorous age of consumption. Opened in 1860, it sidles up to the ever-grand Café Central and likewise bears the hallmark of architect Heinrich von Ferstel, the Habsburgs' blue-eyed boy in the mid-19th century.
Today it shelters upmarket delis, jewellers and chocolatiers; pop in for a mosey even if you have no intention of buying.
