Where do you find friendly genuine nice Polish in London?

This may be a bit of a stupid question, but where are good places to meet friendly polish in London? Somewhere that isn't just another nightclub, because really (would you believe) some of us are looking for a bit more then a one night stand.

(And no, before you ask, I'm not old, ugly, short or desperate - I'm just interested in a bit of cultural diversity and perhaps someone who likes to have fun without being totally drunk!)

try pubs in Ealing?

there is also a Polish social club (POSK) in Hammersmith
