In English, they call it “Heavy Load-Bearing Body” which just for once sounds much clumsier that the German version, and the hyphen looks out of place :-).
Anyway, I have been so close so many times, but never actually seen it and decided to drop in on my way to the Flixbus stop in Alt-Tegel to meet my niece and her girlfriend coming to visit for a couple of days.
Later, while waiting in Tegel, I walked a bit along Tegeler See, And finally, after the girls had arrived, we tried out one of the no less than three Indian restaurant in the area, two in Alt-Tegel and one just around the corner. We opted for Darjiling, which I can’t recommend. The food was incredibly bland.
