Episode One focuses on the 1st and 2nd Arrondissements. Originally the home of French Royalty, the 1st Arrondissement in the heart of Paris is now associated with beautiful gardens and world-class art housed in the Louvre, and is also known as 'the belly of Paris'. Inspired by visits to two restaurants, Guillaume cooks his version of one of the earliest French recipes, artichoke barigoule. In the 2nd Arrondissement, once a very poor area but now a culinary epicentre in the city, he explores the Rue du Nil. This 27-metre street is a foodie’s paradise with many wonderful artisans, providores and restaurants including the Michelin-starred restaurant Frenchie. Guillaume meets chef Gregory Marchland and is impressed by the quality of the fast food from his new venture, Frenchie To Go. Later, he buys fish to make braised turbot with asparagus.
