この料理は、皆でシェアする感じですか？それとも一人分ですか？ — Is this dish meant for sharing among everyone, or is it a single serving? (Izakaya · Restaurant, Formal — to staff, JLPT N3)

Gesture & etiquette

Point to the dish on the menu, then make a 'sharing' gesture with hands, then a 'single person' gesture.

Do not directly take food from a shared dish with your personal chopsticks if you have used them to eat from your mouth. Use serving chopsticks (toribashi) if provided, or ask for them.
