Is it feasible to cook a gourmet tasting menu in a home kitchen?

This is not a question about cooking per se, but about professional cooks outside their day jobs. I have seen a few movies where chefs have a restaurant-grade kitchen and kitchenware at home, all ready to use on a regular basis. For example, in Chef , the titular character quits his job at a fancy LA restaurant after an argument with the owner, then goes home and proceeds to cook the same gourmet tasting menu he was planning to cook at the restaurant.

Is this a realistic depiction? Could he likely cook that menu at home, or would he likely need things present only in a professional kitchen? I understand that chefs might want to invest on high-grade hardware for their own homes, but I wonder to what extent they actually need to have everything they would need in their work kitchen.
