Use Hashi (chopsticks) in order to be different!
There are some different types of suchi such as Nigiri and Gunkan-maki. Gunkan maki is a sushi made by wrapping rice with dried seaweed around its perimeter and placing “neta” on rice. When neta seems to drop if you try to dip gunkan maki in soy source, it is one of very smart manners to pick up Gari (sliced ginger) or cucumber with your hashi and dip them in soy source and then put them on top of gunkan. If you are good at chopsticks, please try it once. If you are on date, you will look very cool and know the culture well!
