"Far down the avenue, quite away from other cafés and standing aside the Hauptallee, was the Krieau, a sort of idyllic little farm planted in a great park. [...]. This was the exclusive resort, patronised only by the distinguished people in art, literature, finance, politics and society. It was here that all the noble dames and cavaliers came to sip their coffee, their tea, their chocolate, in aristocratic seclusion, [...]. Very few foreigners knew of the Krieau; but it was none the less one of the most interesting and curious resorts in Vienna in spring. [...]
And now it was spring, and of course the Krieau was the one desirable resort for Laura and her mother. So several times a week we drove down the Prater and had tea there."

Dafür entstand gleich neben dem Narrenturm ein kleines Bethaus für die Kranken des jüdischen Glaubens des allgemeinen Krankenhauses.
