good bread in shops still holds true
A few months ago I went to a bakery close to where I live (small chain with four or five stores in one city and seemingly no webpage(!)) and pretty much stopped buying break anywhere else... about ten times better than what is found in grocery stores.
Favorites include 'bydgoski'* (made from żyto czesane... what's that?) and szwajcarski (dark with raisins) and roasted potato bread and 'emilki' (very close to American 'dinner rolls' which I'd been jonesing for before I went there the first time)
Their sweet things are also good, sometimes very good but their breads are really amazing.
*it looks nothing like what you get in google for 'chleb bydgoski'... it's round and dark but not dense..
