Kitchen Manager vs. Chef
A kitchen manager is responsible for overseeing the day-to-day back of house operations and administrative tasks. They are usually responsible for controlling costs and managing labor. A chef is typically in charge of recipes, menu items and can potentially share some ordering and staff management responsibilities with the kitchen manager.
Great kitchen managers exist. You just need to know what you’re looking for to find one.
