I like the dining experience while in Japan. Restaurants have kiosks at the entrance taking order and payment. You select the order from the menu and pay right there (cash or CC). The machine prints a ticket and sends the order to the kitchen. You give the ticket to the wait staff. They sit you and begin to bring what’re in the order to you, drinks, appetizers, meals when ready.
Simple, efficient, fast, low touch, low tech, and no tip.
