Rick Stein takes the viewer on an epic culinary journey by sea, down rivers and overland to explore the Far East's diverse food cultures, which have soared to the heights of popularity the world over. Rick travels down the Mekong River to Vietnam. The country's light and fresh food, prepared using an abundance of herbs, includes lots of freshwater fish and flavoursome soups made with thin strips of beef and rice noodles. In Saigon, Rick visits the old stomping ground of his hero Graham Greene, and in Hanoi he meets up with a former employee who delights in the varied and delicious street food of Vietnam's capital city. For the ultimate in al fresco eating, Rick tries the night food stalls in the heart of Bangkok.
