This café on the Ringstrasse thrills fans not only coffee houses, but also of architecture. The interior dating to the 1950s was designed by the ingenious architect Oswald Haerdtl, who was himself a regular guest at the Prückel. And today the café looks as it did when it was remodeled by Haerdtl. Every detail is right, from the lamp to the umbrella stand. The Viennese love it.
