What could I expect to pay at tourist/local prices in Lublin?
have never been to lublin but i'm sure that prices are much friendlier from krakow's. eastern Poland is undiscovered not only for foreign tourists but also for majority of poles. from what i found on the net, regular beer prices in the old town pubs are 5 - 6 zl.
some photos from the old town:

center is being renovated. i belive you'll find in lublin charm of the historical city but it wont be overcrowded like krakow. enjoy
