For example, take this Kona Kanpachi dish (below) from a popular seafood restaurant in Santa Fe. It has a huge menu with over 200 items. The server informed me that they just added a sushi menu to their raw bar. So I review their menu: tuna, octopus, snapper, scallop, and then I see kanpachi. I ordered it: Kona Kanpachi Sashimi with a salad made up of nori, shiso, bamboo shoots, and rice. Then they confirmed my worst fear. The fish was no bueno. I should have stuck with the basics: shrimp cocktail, oysters on the half shell, stone crab claws, etc. Now back to the kanpachi: I removed 2 pinbones from my first bite into the sashimi!! To add to the disaster, the kanpachi was barely fresh enough to serve. It was dry and the fish was pretty much hacked into. (Notice how the slices of fish on the left side are torn instead of sliced?) Then, they placed Mexican rice underneath the salad. It's not a bad thing, but the rice wasn't cooked today. Old and cold crystalized rice will never pass my test.
This was all I could take, 2 SLICES! Now, I'm a chef. I don't like returning dishes back to the kitchen, and usually try to finish off my plates. However, for the first time here in DF, I just politely asked to have it taken off the check. To give this establishment some cred, the complementary shellfish broth they served me, was delicious. This restaurant is actually one of the busier ones in town. Because of their reputation, I would like to go back to give it another shot. However, I'm going to stick with the dishes that they are known for.
This is what sashimi should look like.
