This is the first cook book where I've read all the background / commentary in between the recipes. David Chang provides a frank commentary on his ascent and success. The recipes are also relatively simple aside from some of the recipes under the Ko section. Making your own foie gras tourchon, freezing and shaving it...yeah, not exactly home cooking. Most are fantastic and easily adaptable to modification.
Oh if you're ever in NY, Ko is so worth it. The noodle bar was ok, but a little bit of a let down after the build up and anticipation.
