Rick Steves' Europe Travel Guide | In this program, we'll nibble chocolate cake at an Old World café, and marvel at the indomitable Gothic cathedral at the heart of town. Then we'll tiptoe through the Hofburg Palace, be dazzled by the Habsburg crown jewels at the Imperial Treasury, sniff vinegar and Kraut at the Naschmarkt, and waltz to the three-four beat of Johann Strauss in Vienna's City Park.
