A large hotel-casion in Las Vegas is currently under construction. There will be an Italian restaurant in the hotel that will serve pizza. Management is trying to decide whether to make the pizza themselves or buy it frozen and simply heat it to customer order. There are two major sources of commercial-grade frozen pizza: Ma Ma's products and the Chun-Yee Corporation.
