A Kaiten-zushi restaurant features a revolving belt that carries dishes of different varieties of sushi and sashimi to choose from. The hot dog sushi shown is intended for children although some adults enjoy it as well. These restaurants are popular in Japan because they require little staff. One waitress to seat you and 2 or three chefs to prepare the food and place on the belts. The bill is calculated by the number of color coded plates the customer accumulates. The shops became popular because they brought high quality sushi to the people who normally wouldn't get it. There are approximately 3,000 Kaiten Sushi shops in Japan today.
