Management consultants can be extremely valuable. If, for example, a new restaurant hired a good one with domain experience, a lot of money would be saved and fewer restaurants would fail. How many new restaurant owners have extensive experience with HR efficiency or ordering supplies efficiently or marketing effectively given their target market? Hell, many new restaurant owners have no idea about their market — they’re betting on decor and recipes and hype rather than implementing sound business practices from the start. Even experienced chefs might not know how to budget and plan well. They also might not be good at marketing either.
Management consultants can add incredible value. It’s ridiculous to dismiss their work.

But there is a name for that role already: Head Chef
A better analogy is a manager of an already successful restaurant hiring a consultant to help them reduce the staff's wages and make them work longer hours. Such as an expert on zero-hours contracts perhaps.
