Its very tender and is an extremely fatty piece of steak. It’s definitely amazing but not quite mind blowing. Sometimes in chuck steak you’ll find a piece with fine meat grain and intense marbling, and that’s fairly comparable to Wagyu.
Wagyu is still beef and tastes mostly the same, just much more tender and fattier.
I think it’s because of Americanized potato salad. The kind with miracle whip and tons of corn syrup. I’ve had mayo based salads like this and it makes me want to puke (as an American lol)
I think this plays with the stereotype that weird eccentric middle aged people like weird/gross food. Sort of like jello salad coincidentally (search it up, it is foul).
