Nice place to sit down with a cup of coffee and Viennese pastry. May be very crowded in the evenings though, so better to plan in advance. Also offers a variety of pastry for takeaway.
The cakes are good, although a year and a half ago they were excellent - probably some of the recipes changed. And still - the place has an enjoyable atmosphere, very efficient service and open till 8 in the evening, unlike many places in Vienna.
