Who says fast food can't be superb? Join us as we visit chefs around the world who are redefining the very concept of "fast food." Chef David Chang of Momofuko Ssam Bar in New York City turns out a spectacular meal in next to no time. In Florence, Italy, a tripe sandwich vendor shows us the glories of the city's oldest form of fast food, while in Hong Kong we visit a local wonton noodle shop that has gained widespread fame for what many consider its perfect recipe. In the Gourmet kitchen, we'll show you how to make Steak Diane in a flash, using a very unexpected ingredient.
