That should be Mülheimer Straße, if you compare the photo with Google Street View:

Thanks! Meanwhile, the (classic) photo shop has also disappeared.
For the anecdote: probably I visited the shop then and bought a large supply of film rolls for myself. But not only for myself, but also for the shop where I then had my films developed and printed. The price of film rolls was cheaper in Germany for a private person in a shop than the purchase price for a shopkeeper from the supplier in Belgium! I sold it at the price I paid in Germany and got a discount on my photos in exchange...

Unfortunately only in recent times we see a film renaissance, most film photo businesses just didn't survive until this moment :(
Did you buy Agfa film back then at that shop?

I think in that shop Fuji :-) In other shops I bought also Agfa and sometimes Kodak and exceptinal Konika.
Afga and Kodak launched cheaper variants later, specifically for discount shops and supermarkets. In terms of quality, the cheaper variants were certainly not bad and especially not when they were developed by a professional photographer.
Letting an expensive film be developed in a supermarket or drugstore gave much worse results than having cheap films professionally developed and printed.
