The bikers continue their journey. This time, they are in mainland France, in Provence, and they begin their journey in Marseille, one of the largest ports in the Mediterranean, where the population is as diverse as the Mediterranean itself. They meet Moroccan-born Fatima, who runs a welcome centre where recent immigrants can cook and eat together. The quality of the light in this part of France is such that it has always attracted artists to the region. Dave is a keen artist and, wanting to follow in the footsteps of the impressionists, they visit L'Estaque, a charming waterside community where the seaside snacks are legend. As they travel westwards, it becomes clear that one of the biggest influences here is that of the Romans. They explore the ancient aqueduct of the Pont du Gard, and in the city of Nimes they meet a local food historian and enthusiast for Roman cuisine to find out what constituted Roman-style gastronomy.
