No.1 - Finish your meal with, "Gochi-so-sama-deshi-ta."
Saying “gochi so sama deshita” is the equivalent of saying “Wow, what a feast that was!” Although we wouldn’t deliver such a compliment unless truly deserved, it is standard protocol to say so after every meal in Japan.
Say it to your sushi chef and he will likely bow to you. However, if you visit a Korean-run Japanese restaurant (there are a ton of these), the chef might just squirm awkwardly.
But if the chef is hardcore, he will respond by saying “osamatsu deshita,” which basically means “I’m sorry I couldn’t have provided a superior meal” -- even if, in his mind, he knows that he may have served you the best sushi you’ve have ever had.
