A bad idea: hiring chefs and having them do line-cook style roles.
1) Chefs don't make very good line-cooks.
2) Chefs are expensive.
3) Chefs will hate line cook work and burn out.
4) The entire point of a chef is the unexpected upside: that they might do something great that you never asked them to do.
A seedling of innovation that could grow into a whole new tree of value.
If you find yourself with an army of chefs, the best move is to do a messy bottom up approach.
At least you'll have exposure to the unexpected upside!
