I finally found the restaurant, close to the Marriot North East Hotel in a rather dark alley. One has to know… Off Xiaoyun Lu. Pretty big, rather empty when I was there with a Filipino band playing nearly for me alone. Good choice of German beers.

Did not try the food yet, they have the typical variety of German dishes. Said to be run by a Chinese coming back from Germany. Prices seem reasonable but I wonder about the quality of the food: some of the dishes need to be done “freshly” and cannot be reheated, with so few clients that might be a question mark.
