The most remarkable feature of conveyor belt sushi is the stream of plates winding through the restaurant typically in a clockwise rotation to make it easier to grab the plate as it passes by. The selection is usually not limited to sushi; it may also include drinks in Tetra Paks, fruits, desserts, soups, and other foods. Beer can be ordered from the attendants, often served with an empty plate to keep track of the bill.

Some restaurants have RFID tags or other systems in place to remove sushi that has rotated for too long. Some inexpensive conveyor belt sushi restaurants may imitate an expensive dish using less expensive ingredients. For example, they may replace chopped fatty tuna belly meat with other fish meat. Some larger chains can keep down costs for quality food by ordering in large amounts
