This week, Chef Anthony Bourdain continues his guest-blogging stint, filling in for Chef Colicchio:

What is a "chef"? A chef is a cook who leads. A chef is someone who knows how to cook and who can also run a kitchen. Leadership skills are required. Management skills. The ability to execute a vision with consistency. Doing these things means that you are constantly making decisions large and small. The ability to make a brilliant, creatively-dazzling and delicious plate of food is near worthless if you can't do it again and again--exactly the same way--at high speed, under the gun, hung over, after a night of fierce Negroni drinking...while listening to Mexican thrash metal. And you can't do it alone.
