Tech-focused conveyor belt sushi chain, Kula Revolving Sushi Bar, uses prizes as an incentive to get diners to order more food. A customer who eats 15 plates receives a small toy such as a keychain or stickers via a machine. The mostly California-based chain debuted its first Austin, Texas, location earlier this year.
