"The sample of salmon cells served up in Portland cost $200 per sushi roll (six pieces)." https://www.hakaimagazine.com/features/the-faux-fish-coming-...

For reference, fresh, wild, King Salmon, which is only available at certain times of the the year (depends on your state/country), can be $30 a pound or more. At $100 or $200 a pound, they don't have that far to go to be in the ballpark.

I could see people paying that sort of money for 4 ounces of nigiri in some endangered species.

Cruelty free blue fin tuna, anyone?
