At forty, he is the head chef and one of the owners of Eleven Madison Park, a restaurant in Manhattan that is celebrated around the world for a casual clockwork opulence. Symbolically, Eleven Madison Park also serves as a sort of Buckingham Palace: the heart and focal point of an aggressively expanding empire. Humm and his business partner, Will Guidara—the two men work so closely that they're always talked about in tandem, like the Glimmer Twins of gastronomy—oversee a renowned restaurant, the NoMad, in the eponymous Manhattan hotel, and a warren of bars and nooks in the same space. They're planning to open a branch of the NoMad in Los Angeles in the coming year, as well as a new fine-dining sanctuary in a luxury tower at 425 Park Avenue. They also intend to roll out a group of fast-casual spots under the rubric Made Nice. To observers who murmur enviously about the duo's seemingly effortless march to power, it can all be a bit much to bear—the money, the air-kissy acclaim, the unsinkable Disney smiles. Theirs is the kind of success that makes mortals smirk.
