If it's not that time, simply use the in-game wait system to reach that time instantaneously, and then call for the waiter. As long as it's between 7 and 8 at night, you can call a waiter to come take the food upstairs. Once the food is cooked, go ahead and approach the intercom on the wall near the kitchen's entrance. However, without a fairly high Survival skill, you'll need to use a high Intelligence check to cook while replacing the human flesh the recipe called for with something a little more imitation. Go ahead and examine it, which will give you the opportunity to cook. There should be a pan sitting on the stovetop. With the angry and egotistical chef out of the way, approach the stove he was located near. But that's good news, because now you can get down to creating a little culinary creation of your own, if you managed to convince Philippe to leave behind a few recipes for you that is. We even followed that up with a Medicine skill line that upsets him enough about his traumatic experience with his family that he leaves us alone quicker than we would have initially imagined.

While there are multiple ways to do this, we found that using our Barter skill to convince him that you work with a publisher putting out a cookbook did the trick. Medicine, Barter or Speech skills of about a 50 or over will do the trick the idea is to basically upset Philippe enough (or otherwise convince him) so that he goes away, leaving you alone in the kitchen to do what you will. After more conversation like that, you'll eventually start to get various kinds of skill checks. Be rude and aggressive right back to Philippe. The key with Philippe is to convince him that you're someone you're not.
