My wife's family is from Poland, so I often have a Polish lager thrust in my hand when visiting family. Zywiec is good, as is EB. My favorite pale Polish lager is probably Okocim "OK Beer", which you can get in the can nowadays. I wouldn't say that any of them are better than comparable beers from the big German lager breweries, but they're all definitely tasty brews that I will grab if I see them fresh.
