Ok font of all knowledge - I am off to Berlin (again) at the beginning of December for three days to check out the Christmas markets. Well my missus is doing the markets and I will check out a bar or two. We went to Berlin earlier this year and really loved the place hence us going back again. So can anyone recommend some off the beaten track sights to check out?

We have done the main stuff like Museum Island, Brandenburg Gate, Reichstag, Fernsehturm, Checkpoint Charlie, Spandau, Potsdam, Gleis 17 and Charlottenburg Palace. When we were there last time we stumbled across Treptower Park and thought there must be more to see in the old Eastern part that was worth checking out. If you look at the places to visit in Berlin we have been to most of them so was looking for something a bit more off the beaten track and a bit quirky.

So anyone got any suggestions? Also any decent bars worth a visit for a genuine German type bar and not a tourist magnet. Thanks in advance.
