I'm not worried about that one cook that I have, because I've known him for a long time already, I've paid him quite well, can be consider above average. Also, some of the receipe are still secrets eg. black pepper, mushroom, garlic sauces etc...the main paste of these sauces I still make them myself. So I believe it's a non issue. and my cook has been there for 4 years already, and I admit sometimes he cook better than me. I also asked some of our regulars, they said no different in taste, still as good like mine, if not better.
