Delphiandomine, is it really that difficult to follow simple rules? you could choose ANY thread on this forum and post your senseless babble on it but you insist on posting here when I specifically asked you to stay away. you know what this thread is about, the criteria I requested and you know you don't satisfy them all.
When you can stay in Poland without being subject to immigration control, then we'll talk.
Bottled beers are a good idea in PL - some bars keep the draught beers very poorly. I can think of one on ul. Wilcza where there's something amiss. Perhaps, just perhaps, the uniformity of Polish beers allows them to attach a cheaper barrel to the pumps.
It's not the barrel itself, but rather the lines to the barrel. I know someone who owns a bar who explained it all very simply for me - basically, you need to clean the lines once a week. This is costly - the bar in question was losing 10 litres a week per line, but it meant a way, way, way higher quality of beer. That's why sticking to bottles is the 'safe' bet in Poland - I very much doubt that most places are cleaning the lines even once a month! It's also a lot to do with the quality of chemicals used - once you've been to my friend's bar, you can really, really taste the difference.
Incidentally, the Ukranian Obolon isn't bad at all for a mass market beer, though it's tricky to find in Poland.
