What to do at Sushi Restaurants
Clean your hands at first, then order a drink.
Green tea (it's called agari in sushi restaurants) is the best drink with sushi.
You can order a set of sushi with a fixed price or order your favorite sushi pieces as you eat.
It's nice to ask the sushi chef for his/her recommendation of the day.
If you are not ordering a set of sushi, it is good to order a few kinds of sushi at a time, instead of ordering a lot.
Put soy sauce for dipping in a small dish provided.
To eat sushi, it's common to use your fingers.
When dipping sushi in the soy sauce, do not dip whole sushi. Just dip the end of the sushi as you eat.
Try not to ask the sushi chef to bring you things like a drink or your bill.
It's nice to offer to buy your sushi chef a drink if he/she is doing a good job.
