Cukiernia Sowa ★ 4.0
Cukiernia Sowa at Stary Browar on Półwiejska 32, Poznań is the city-centre branch of the Bydgoszcz-founded 1946 patisserie chain, good for karpatka, sernik and the Bydgoszcz rogal bydgoski variant year round.
Tip: Eat the karpatka or sernik on weekdays; the rogal bydgoski here is Bydgoszcz's PGI workaround, not a certified rogal świętomarciński.
Worth the queue: Karpatka
