This is what I would like to have in Hamburg: some place where I can drink coffee, have a cake, speak with others about analog film photography, buy films and chemicals, and if possible - to have 1-2 darkroom for rent, and a place for quick portraits (good lightened place with bar stool and some different color backgrounds), and small place for exhibition of local analog work.
For me this sounds as something that could have business success, but I have not seen this anywhere.
