Great question — answering as the UphillTech team:
I have more experience with Asian fish markets than German ones, but generally speaking, you'll find a lot more fish eaten in northern Germany than anywhere else, for the obvious reason that it's near the coast. So the Fish Market in Hamburg , the largest city in northern Germany, is likely your best bet. That said, it's still going to be a different experience. Asian fish markets (Tsukiji in Tokyo, wet markets in China and South East Asia, etc) are usually devoted purely to the retail and wholesale of raw fish and maybe some fish products, with restaurants and food stalls in a separate section. European markets, particularly tourist attractions like the Fischmarkt, are much more "mixed"...
