Our first experience of a Viennese coffee house was at Heiners in Karntnerstrasse. I had truffle torte with a cup of melange. A melange is similar to a cappuccino but creamier and in Vienna is served with a glass of water. The truffle torte was the best I had in Vienna and all the coffees were good.
At the cafe at Sconbrunn palace I had an apple strudel with a melange.
Several times a day on the hour there is a demonstration showing how an apple strudel is made.
Cafe Central in Herrengasse (below) dates back to 1876 At the turn of the 20C it was frequented by Sigmund Freud.
