Café Central - Imperial Café with extraordinary vaulted ceiling interior; best dessert case; also good menu beyond coffee and desserts.
Café Hawelka - Family-run, artsy café which has hosted leading innovators for decades; cluttered, wooden furniture crowds the café; known for serving Buchteln, which are jam filled buns, later in the evenings.
Demel Café - By many accounts the originator of the Sachertorte. But get the violet ice cream sundae or the afpelstrudel instead; sit upstairs so that you can pass through the pastry kitchen.
Café Wortner - Voted best café in Vienna; especially nice in the spring/summer in the front garden
Café Sperl - What you probably think of when you think of a Viennese Café
