My favourite bar
My favourite bar of all is linked to Union Legend Torsten Mattusschka - Tusches Kick & Rush (Am Generalshof, Köpenick) . Lots of football memorabilia, footie on the TV - often packed out on matchdays. Very friendly with a good atmosphere...but remember that its CASH ONLY and its East Berlin so don't expect them to speak English !
When I go to Tusches I have been known to partake in one or two (possibly more!) Pfeffis - an East German Peppermint Liquer. Its not as bad as it sounds ! I have noticed though that it seems to lead to getting lost,bruises,falling over & memory loss !!! Prost !
