In addition to vivid descriptions of the taste and texture of the foods he discovers, Zimmern also provides a short history of each dish. Some of the locales Zimmern has traveled to include Ecuador, Taiwan, Iceland and Minnesota (because not all "unique" foods are found in exotic locations).

Anthony Bourdain had no reservations about a move to CNN.
