In a blurb about the new Momofuku Milk Bar Cookbook, this description of the difference between David Chang and his dessert chef Christina Tosi:

In the Momofuku kitchens, where chefs are hospitalized for anxiety-related skin diseases, Tosi is calm. Tosi doesn’t yell. There is no need. She is Samantha from “Bewitched”—she is all serenity, because she knows that things will work out fine in the end. If someone screws up in a Dave Chang kitchen, Chang will scream and rage and tell the person he has no integrity and might as well be working at KFC; then he will have to lie down for a day to recover. One imagines that if anyone ever screwed up in a Christina Tosi kitchen, she would wiggle her nose and, with a magic ping, that person would simply disappear.

Also, Chang bought her 240 Take 5 candy bars for her birthday and challenged her to eat them in a month.
