DON'T dip the rice part of the sushi in shoyu, just a corner of the fish.
DON'T put pickled ginger on a piece of fish.
DO offer to buy the sushi chef a beer or sake. "It makes a good bribe," says Nao Saba, general manager of Mori Sushi.
DON'T ask for a California Roll. It's a dead giveaway that you're a neophyte.
DO ask questions about the fish — where is it from, what part of the fish is that cut from, etc.
DO use Japanese words for fish if you know them.
DON'T order all the sushi you want at once. Sushi should be eaten right after it leaves the palm of the chef's hand.
DO finish your meal with tamago (egg custard), vegetable maki (cut rolls), such as cucumber roll or oshinko roll (sour plum with cucumber and shiso).
DO eat around. You may need to try a few places before you find a sushi bar and chef you like.
DO go back once you find a sushi bar you like. The experiences that follow promise to be even better than the first.
