Frankfurt. Woss it like?

also the statement that foreigners are not welcome in clubs leaves avery bitter tastes afterwards, especially when I have never heard of such a thing and maybe of course being german after all, but I don´t wanna start a new discussion alltogether...

Well tell your bouncers not to be such dicks, then :-)
Did your foreign friends try getting in on their own? Were they English?
They seem to fucking hate the English. Probably something to do with all the financial sector workers, so who can blame them. We could never get in on our own, but send the two handsome single lads to go and pull a local bird or two to come with us and suddenly we were allowed in.

As for the beer defence, all I can say is prove it by supplying some.
All I found there was horrible fizzy lager, which doesn't qualify as beer.
