The best choice is sushi. No need to persuade him to eat rice, it's all wrapped in it anyway. Two or three is enough without him noticing. I seriously doubt whether the rice here is much better. The rice in any store is fragrant, glutinous and has a strong grainy texture.
The eel is too fat, and there is a rice bowl that tastes like our bacon. The taste is okay. Although the quality of sea urchin is okay, everyone in this group despises its fishy smell.
