When you go to a sushi restaurant, especially in Japan, you’ll often note how clean and sterile the environment can be. Much more so than your average restaurant, sushi restaurants concern themselves with the cleanliness of their surroundings and the product itself. It’s key to the customer experience that the fish be perceived as safe and that the establishment they choose to visit have a reputation for high standards.
In Japan it is common for some sushi restaurants to prepare the sushi beforehand and place it on a moving conveyor belt for customers to choose what they want. Rather than consuming time with individual orders, this assembly line of raw fish keeps customers eating and the sushi restaurant humming along.
