Hmm, you sound a bit condescending (and angry). Eating sushi doesn’t make you some kind of intellectual. Otherwise, I’d be brilliant!! I’ve eaten sushi all over the world and have never noticed “red” toro on the menu. Toro (yummy), yes, not sure where the red comes in. I did a quick internet search and didn’t find anything. I’m sure it exists but I’m not sure how common it is. I think torigai is a shell fish, don't recall seeing it on a menu. Unagi is a pretty common offering at sushi restaurants, not sure why you threw that one in, perhaps you thought it sounded exotic and scary! It’s quite yummy with a slab of avocado. It’s a shame you don’t find salmon, tuna, red snapper and the many other delicacies still available in sushi restaurants worth your effort, that just means more for me!!!!! I guess I’m one of the ones eating all the fish since I prefer the sashimi, I don’t want to waste time with the rice:).
I wonder if this is the same Hiroshi Hatanaka that I knew back in the 60's. He was a Japanese national, a scientist, studying at Harvard and he briefly dated my apartment mate. His manner was very abrupt and pompous, and pretty soon we all decided he was not someone we wanted to spend time with. One incident: we were seated at a table and suddenly Hiroshi brought his knees up against the bottom of the table so forcefully that the table made a sharp cracking sound. It turned out that my small dog had brushed against his leg, and Hiroshi was apparently frightened. Instead of being embarrassed, he laughed nastily and said that in his laboratory he would cut a little dog like that into pieces.
We all decided then that he was a nutcase -- unfortunately his career has probably put him in the position of hurting and killing plenty of animals.
If Toro is not a deep and bright red it is either old or rotten? :)
