Vienna Old Town Layover: Demel Treats, Church String Quartet, and Zwölf Apostelkeller Schnitzel
Start with a walk around the old town packed with churches, shops, and museums in the historic center. Hit Demel for chocolate and that excellent pudding-like dessert with plum sauce. Book tickets for a string quartet playing Mozart, Bach, Vivaldi, and Beethoven in one of the big churches with unreal acoustics. End at the 12 Apostles spot, the cool underground bunker-like old stable restaurant, for the very good schnitzel.
