Hip restaurants around the world, such as Noma and In de Wulf, are adopting a more contemporary approach to service; the restaurant's chefs not only create the food, but they also serve their own dishes, which makes for a very interesting encounter.
You can tell that they are not professional waiters because they appear not so refined at the art of serving. However, it is a brilliant idea which gives guests the opportunity to interact with chefs, and chefs the chance to get out of the kitchen and meet the people they are cooking for. Justifying the new trend, one could argue that who better to explain the content of your dish, than the person who is responsible for it. It’s a win-win approach.
And it is kind of flattering to have the chef come out to your table and bring the food.
