I found this graffiti - humorous and colorful drawings on the wall of the building which housed Checkpoint second hand store at Mehringdamm 57 (Kreuzberg). That's why I entered the store. The drawings covered the wall till the second floor and were in real a very interesting and smart advertisement.
I found stores and esp. the largest department store called KaDeWe pretty crowded at Saturday midday.
Most stores and department stores were closed on Sunday in Berlin. That's why Berliners used to do shopping just on Saturday. If you don't like a little more people, do shopping during business days.
Apart from mostly expensive stores along main shopping streets there were many worth visiting smaller and inexpensive stores located just around the corner. Usually they were not so easy to find out. Sometimes there were large advertisements and direction signs put on the walls of houses just like this one on my picture showing the way to large second hand store "Garage" at Ahornstraße.
I was talking with Germans about cars a few times. Surely they were proud of German cars and especially of top-class models of Mercedes. No wonder. The company is well known of top quality, the most prestigous cars and... the highest prices but worth the cost. Whatever you think it would not be the best option to start the discussion with a German at criticism of their cars.
Walking along main shopping street called Kurfürstendamm or shortly Ku-Damm I paid my attantion to the large store of Mercedes-Benz with quite many people inside on Saturday midday. If you like Mercedes and want to see the new and concept cars of the symbol of German motorisation it's place to stop for you.
Where it was?
Mercedes-Benz-Autohaus Dagefeld at Kurfürstendamm 175, southern side of Ku-Damm at corner of Knesebeckstraße. U-bahn: Uhlandstraße (last station of U19).
There were quite many such structures as on my picture around Berlin, especially along its main streets and boulevards. They were more than just a movable or temporary small shops for selling newspapers and magazines.
They offered many more: postcards, cigarettes, some gifts (small mascots of Berlin bears), tickets for public transportation (but not one-day tickets) and other small things. Everything at normal prices even at famous shopping boulevard - Kurfürstendamm.
Excuse, it's more worldwide sign of safe and usually upscale districts than Berlin local custom tip.
When I first drove around Berlin's district of Charlottenburg, looking for accommodation after... midnight I could see few people still walking around - nice surprice. Next day I could see... look at my picture - how to call these glass advertising-boxes with shoes, clothes for sale inside put on a street in English? They were located along main shopping street called Kurfürstendamm or shorter Ku-Damm.
My simple conclusion was: Charlottenburg was very safe district either at day and at late night. And it was upscale (= expensive) district as well.
