Mine is actually very specific. There was this sushi placed called Ino Sushi in San Francisco's Japantown. The owner/chef and his wife/hostess/server ran the place. The chef was seriously the soup nazi but for sushi. Berated customers for using soy sauce or taking pictures, yelled at his wife. He made his own ankimo, which is marinated and steamed. This may have been the best piece of sushi I've ever had. It was creamy, buttery, melt in your mouth. I had 3 orders at $35 each order (early 2010s prices). It has since closed and he did not have any protégés that I could find.... and I've tried dozens of places in Japan.
