Perfection costs a whole lot more than really, really good because costs go up exponentially.
You need multiple times the staff on hand to cook and server everything at the same time, and they should be highly paid professionals. You need to be able to discard the majority of your food supplies, which already cost a lot more than normal, to have the perfect version of every dish. The setting probably costs a lot to set up and clean up after, and attention to detail costs time and money.
It is a huge waste, but that is why it costs so much.
