For lobster, Sea urchin, and Abalone, i’ve never had anything in a sushi restaurant (japan, US, elsewhere) that is anywhere nearly in the stratosphere of what was hand-caught.
There are secondary and tertiary levels that you would never taste if you bought it from a market.
the lobster in a tank starts eating its own meat and deteriorating.
Pursue that food. it’s the purest and best way to eat unadulterated, PURE food as God and Nature intended.
