I was unaware you were Poznan based until I checked your profile. Was working there a lot over summer, did you visit the cargo container? madness.
Oh yes - utterly surreal at times. It's sad that it's closed for winter now actually - it was great being able to go there and not have a clue what you might find, though there were some really dreadful "acts" there too! But really, I liked it most in the afternoons.
The Belgian beer bar remains an eternal favourite though the owner (slawek?) took a distinct shine to getting me plastered on his most dangerous brews :)
Christ, that place is lethal. Delirum Tremens is just plain dangerous :(
Za Kulisami, however, remains my eternal favourite for smokey nights collapsed in a heap.
There's quite a few places like that - there's one rather strange bar near U Hoznika that seems to exist solely for somewhere to go after you get kicked out of everywhere else. I don't even know its name (or if it has a name!) - but it was a really odd place, just for the utter collection of weirdos that end up there.
The thing I love about Poznan is the way that new bars always come and go - though it's annoying when you find somewhere nice, only for it to vanish a few weeks later!
The only thing I dislike about this city is the way that many pubs seem to insist on playing music at an ear-splitting level. I'm really not sure why - wouldn't they sell more if people can talk more?
