Bad-boy traveling chef Anthony Bourdain has sampled the world’s most revolting foods (eyeballs, cobra hearts) in the most exotic locales (French Polynesia, Machu Picchu, Cleveland) in No Reservations’ five seasons. Season three, new to DVD, is a high point in Bourdain’s unscripted search for foodie — and other — thrills. He goes to Namibia to eat hog’s anus, one of the only meals that has made him sick.
