I did something similar to what Erz described above. I broke into sushi slowly... a few Cali rolls here, a shrimp nigiri there... small fish, pardon the pun. Then I went out with my sushi enthusiast friend who insisted that I order some sashimi. He recommended the small plate consisting of tuna, salmon, red snapper, mackeral, etc. I did and ordered hot some warm sake to go with it.
I get the plate and it is anything but small... there is so much raw fish on this plate. I was intimidated. But I was determined to go through with it so I started going at it. By the time I made my way to the salmon... the texture of all the pieces of raw fish that I'd already eaten was playing tricks with my mind. I was not having fun anymore... that's for sure. But my friend kept insisting that its bad etiquette to leave sushi on your plate... so I kept going and finished my food.
I wanted to die.
Then next week... I wanted more.
