WSJ Interview with Chef Sang Yoon (of Father's Office)

Love this answer:
"I'm a firm believer in Tommy's double chili cheeseburger. I eat fast-food burgers like there's no tomorrow. In-N-Out is pretty good. A McDonald's Quarter Pounder with Cheese is a classic. I grill at home, but I've actually never made a burger for myself."
And this one:
"I do everything differently here [at home] than in the restaurants. See, I have Heinz ketchup in my refrigerator. It's not for me. It's if someone comes over and wants it.
