Under two pretenses ... do whatever you want. There is no noodles with gravy, but there are raw materials. I can make it for you now.
There are three pretenses: .......... has everything he wants to eat, a big restaurant, and he is well prepared. As long as it is on the menu, he can order at will.
There are four pretenses: .......... can eat whatever he wants, and he has a big restaurant. He is well prepared to order whatever he wants, whether there is a menu or not.
