If you like trying of the local traditional culinary specialties, I have some tips what taste in Prague during ESUG:
Svickova (s karlovarskym knedlikem)
Pecena kachna (s karlovarsk��m knedlikem a cervenou repou)
Ovocne tvarohove knedliky
- attention: sweet
and of cours the Czech BEER :-) If you are looking for beer from smaller local producers (Marcus, Denis?), you should start on this place:
