Eating at the Golden Pearl wasn't purely just ordering form a menu. It was almost like renting a car - you needed to choose the kind of plate you wanted first and then add dishes on top of that. There were silver, gold and diamond plates. Silver plates were for the 10k and below price range, gold plates for 10k to 80k, and there was only one type of diamond plate which costed 88.888.
Depending on the plate you chose, the cheapest you could get was 2.222 and the most expensive was 88.888.
Chong Yuanyuan ordered the 8.888 silver plating and then went into a room. Inside the room, you chose the dishes you wanted from a touch screen.
Looking at it, their meal was going to cost more than 15k. And then you also had to take into account what sort of drinks you wanted, f.e. high class wine would cost a lot.
