The Viennese Kaffeehaus isn't a café; it's a public living room you rent by the cup, where one Melange (espresso under steamed milk) buys you an afternoon, a newspaper, and the right to be left alone. This walk strings five of the great rooms together at the only correct pace — slowly.
Start grand, at Café Central, the pillared hall where Trotsky once did his reading. Cross to Demel on the Kohlmarkt for a slice from the imperial confectioner, then down a lane to Café Hawelka — small, dark, family-run, the opposite of Central in every way that matters. Take the short detour to the Loos American Bar, a jewel-box of marble and mirrors, just to stand inside Adolf Loos's 1908 room.
Then south and a little out of the centre to Café Sperl, where the billiard tables date to 1880 and the velvet is honestly worn. This is where you finish — take a paper from the rack, order something, and don't hurry. Karlsplatz is a short walk when, eventually, you leave.
