Can you have too much Vienna? I doubt it somehow, although you can certainly push your luck with its patisserie.
Today we went to the Kunsthistoriches Museum, which was amazing. In addition to the priceless works of art, it had an awesome cafe, where we had lunch and coffee.
More artwork was then looked-at, followed by hot chocolate and cake at the Cafe Museum on the way back to our hotel. I got to try something on my “to eat” list – this little tortchen is a mini black forest gateau. The cafe itself was ok, if a little odd with large metal balls suspended along the ceiling.
