Is there someone from Berlin here?

I do know of an Austrian living in Berlin. He's got a funny moustache.

In Berlin the common beer brand is Berliner Kindl. You can look for yourself at the local supermarket.
if you like honey, try some Odins Schlossbräu. it's nice, but a bit expensive and a bit rare, atleast in Hamburg.
Some of the large Gaming shops are:
Gamestop http://goo.gl/maps/2zjAq
Media Markt http://goo.gl/maps/Kzaxu
Saturn http://goo.gl/maps/IolXA

Real men drink schwarzbier. Doesnt matter which brand.

PC game shop? We do have GameStop's in Berlin, but as everyone knows they are terrible.

MediaMarkt sells old games for 5 or 10 € might be worth looking into.
