From season 2 of Gordon's Great Escape. For the second series, Gordon goes back on the road doing what he loves most: searching out the best food in the world and testing himself in extreme and demanding situations. This time he's not just taking on one country, his appetite for adventure will take him through four of South East Asia's most exciting culinary destinations: Thailand, Cambodia, Malaysia and Vietnam. In this clip in Hanoi he grapples with the ferocious Madam Duck and begs her to reveal her secret duck recipe. He also rises to the challenge of broth maker Zi Hai to sell over 80 broths in a tiny boat at a floating market in the Mekong Delta.
