We elect to go separate ways. Mungo heads off for x-rays, passports and who knows what else. I use Moovit for first time and immediately take the wrong bus. After walking to Karlplatz head to Karntner Str but useless, so retire to Cafe Schwartzenberg.
After leisurely grosse brauner and stop at nearby würstelstand, walk to Maria Hilfe Str for a spot of shopping. Then home by crowded U6.
