Kura Sushi, a kaiten sushi joint in south Namba, Osaka. Really cheap but decent conveyor belt sushi. Put your plates in to a slot in the table for a chance to play a game at your table for small capsule toy prizes. Either take plates off of the belt or order anything you want from the touch screen at your table.
