With the exception of a brief period during the Second World War, this family-run Viennese gem has been greeting customers in search of coffee since 1939. While the original owners have passed on, their welcoming spirit lingers and little else has changed over the decades, except the addition of an espresso machine. The speciality, Buchteln, is served warm and delicious in the evenings, and instead of searching the menu for a latte (which you won’t find) opt for the Einspänner – a strong black coffee topped with whipped cream. The smoky notes of the coffee compliment the dark interior, which was designed by Adolf Loos and is hung with works of art by artists known (including Andy Warhol) and unknown – tokens, is it said, that were bartered for coffee. An exchange of art for art, if you will.
