There are a few Batidas around the city, but for the full Viennese coffee house experience you need to get yourself to the flagship on Marszałkowska. Grab a seat by the huge windows in the elegant, high-ceiling dining room and feast on a good, brief menu featuring - amongst other things - excellent salads (the smoked salmon is a treat). The cake selection is out of this world, and prices are not as high as you might think. Also at (C-4) Pl. Trzech Krzyży 18.
