Two trips to Vienna (one solo in Sept and one with Bob in Oct). The train ride is 6 hours each way via Budapest. When I visited Vienna alone I hit the last weekend of summer weather. I was able to sit outside with my plum cake and grosser brauner at Cafe Sperl. I also tried the plum cake at the historic Cafe Hawelka. Better at Sperl.
When it rained on the next visit, Bob and I and everybody else in Vienna had the same idea: to go to Cafe Demel


The nut cake is almost gone but the cup in my hand contained hot chocolate with Bailey's and schlagobers, one of the best words in the German language. I'm trying really hard not to blink at the flash.
BUT the best dessert was at the Albertiner Keller:

Poppyseed-honey mousse with sour cherries. In a little glass preserves container. What??? You can see in the top left corner what was left of Bob's sachertorte.
More later on art and buildings!
