Vietnamese food is widely regarded as one of the world's healthier cuisines. There's nothing particularly holistic or nutritious about this traditional favorite however. A local variant on steak and eggs, the dish is a calorific wonder. Steak is sautéed in butter on a sizzling platter, an egg is added and some hot-dog style sausages complete the picture. Mop it up with a banh mi baguette and wash it down with a glass of potent coffee.
