What are things to see/do in Berlin, Germany?

What are some fun things todo in berlin germany and where would you recommend going?

• me and a friend are going for the weekend, looking for things to do while where there

• Answer:

  Use the search for my former answers on this topic. I think a weekend is too short to see all of Berlin, but for a short impression: If the weather is fine, try to catch at least a city tour by bus and a guided tour on one of the boats crusing the river Spree and the canals. If the weather is bad, visit at least one of the museums (not necessarily one of those on the museum island) and go to one of Berlin's cinemas where they play your most favorite American movie, just to hear the actors dubbed in German (no, no subtitles here). And as to the rest: Just enjoy!
