It doesn't meet your 10 generation bar (not sure there would be even 4 generations of non Maori baking in New Zealand) but I can name 3 second generation bakeries/kitchens and the staff work very hard and have high standards. The things they make get high prices and they appear to be doing very well. I went to school with 4 of the younger generation and they now mostly run one of the companies.

>Dude. You bought, hooker and sink, some bullshit ad from the local 'artisanal bakery'

The world is larger and has far more tradition and expertise in food that your local USA neighborhood, "dude".
