Is there a store in Berlin like the Paris institution G. Detou, a small store that offers gourmet products -- mostly canned, bottled, packaged, cryovaced -- at semi-wholesale prices? I usually go there for their Nestle, Belgium-produced thick liquid concentrates of beef, veal, and fowl, etc. that are like industrial strength demi-glace. I suspect the same product is available in Berlin, but the question is where.
In the absence of a store exactly like the Paris shop, where might I find a shop in Berlin that would have a variety of high quality gourmet products -- please note I am not talking about ready to eat.
Several years ago I did identify on-line several German produced demi-glace type concentrates, but their names now allude me. However the Nestle food service product is the likeliest to be available now.
Thanks for your suggestions.
