As to Vodka. I can recommend you the best I've ever drunk - Siwucha
"Fly or not, never LOT"
or in Polish: "Polec LOTem, nie wrocisz z powrotem" - I came by those slogans honestly - over a bottle of Belvedere shared w. some LOT pilots.
I agree though, Poland is a great place to visit - the spirit of the people, their openness, hospitality, wit, creativity, make it a very special experience.
