George
I think the photo wasn't shot in Bulgarian town of Kavarna (Каварна), but somewhere in Czech language area (Protectorate of Bohemia and Moravia or even Sudetenland), because kavárna means caffé in Czech language. Note the accent on the second letter a in the word kavárna.
Also, you might have noted that all of the signs are in Latin script and none in Cyrillic.
