Purists typically don't like fancy versions of ethnic cuisine, but they seem to have made an exception for Rick Bayless' restaurant. Though he's a top celebrity chef who is often away filming his TV show or doing a book tour, to his credit we didn't receive a single complaint about him not being in his kitchen. The restaurant's success is built on the following principles: Craft a Mexican cuisine that adheres to tradition but is prepared by chefs with formal culinary training. Result: The snapper in a Oaxacan mole sauce and the puerco pipian verde are more refined than they would be at your typical Mexican restaurant.
