I’m with you on the sushi. I tend towards sashimi and sushi pieces made with the more tender, buttery fish like salmon, tunas, kanpachi, hamachi, and the like. I hate trying to bite a piece in half and having it hang with the integrity of the rice crumbling beneath it. The only solution is to hurriedly shove the whole thing in your mouth with all of the awkwardness that comes with it.
Yuck.
I also agree with the mushrooms. Seems like one thinly sliced 'shroom would have sufficed.
