In 1946 Felix Prousek managed to open additional branches. He also brought the idea of”fast coffee and cake”, common in Italy, to Vienna. Austria’s first espresso machine was put into operation in 1946 in the AÏDA branch in Wollzeile in Vienna I. Since then, AÏDA has been known as “Café-Konditorei”. A true innovation that was enthusiastically greeted by the people of Vienna.
