and yeah, Polish beer is awful. i always drink imports here.
Lech Pils is very good, but it's only available in Wielkopolska.
Incidentally, you do know that "imports" are very often brewed locally in Europe? Just because it pretends to be an import doesn't necessarily make it one. And the difference in taste can be astronomical - anyone who's tasted UK Stella Artois or San Miguel and then tried the "home" version will understand what I mean.
Unless something has changed, Heineken is a great example in Poland of this - it's sold as a premium product, it pretends to be imported - but nope, it's actually produced in Poland by Grupa Zywiec.
Carlsberg as well for that matter.
It's actually very difficult to get something that was genuinely imported into Poland in an ordinary pub.
