Shopping Bag

The food item you are referring to is most likely a "shopping bag"-style sushi roll, also known as a "conveyor belt" sushi or "kaiten" sushi. This type of sushi is served on a rotating conveyor belt in restaurants specializing in this style of cuisine, allowing customers to easily select the plates they wish to order. The "shopping bag" style refers to the shape of the sushi roll, which is tightly wrapped and resembles a small bag. These rolls typically include ingredients such as rice, fish, and vegetables, and are often topped with sauces or garnishes for added flavor.

It's worth noting that the term "shopping bag" is not a widely recognized or official term for this type of sushi roll, and its usage may be limited to certain regions or restaurants. If you are unsure of the proper name for a dish, it is always a good idea to ask the staff at the restaurant for clarification.
