Welcome to Berlin

I have finally arrived in Berlin and I've had a couple of hours to try and fiond my way around. Can anyone explain how the transport system works? Any friendly Blipfoto people in Berlin that speak English who'd like to help me, i'll happily thank you with a beer!

I am staying in the former East Berlin. It's quite funny to sit in a restaurant and hearing the soothing tunes of Theme from Fame and Level 42's Running in the Family. It appears the wall has fallen but up to date music hasn't quite made it over!

I am sure I shall be boring you over the next 3 or 4 days with the sights of Berlin. Please bare with me, I'll try and make it interesting..
