The Susta strudel is an establishment you simply have to know about to find. There are not signs, directions, no online presence, no advertising, nothing. Mr Susta bakes his strudels in a side street of the Zizkov district in the shadows of the Vitkov National Memorial (a sight we definitely recommend that everyone visit), in the "kocarkarna" (formerly a small storage room for baby carriages) of a prefabricated panel house from the 1970s.
