The Mitsukoshi Isetan Food Specialty Stores Appreciation Festival, held on the basement floor of the Isetan Shinjuku store until March 4th, is attracting attention for its "Pain Perdu au C.B.S.", a French toast created in collaboration between French caramelier HENRI LE ROUX and Parisian luxury food store HEDIARD. "Pain Perdu" means French toast. Made with HEDIARD's brioche, the French toast is topped with Henri Leroux's signature caramel mousse, "C.B.S." The fluffy golden-brown brioche and the caramel sauce, made with salted butter and nuts from Brittany, France, combine in exquisite balance. The price is 630 yen. During the event, demonstrations on how to make Pain Perdu are also being held in-store. According to the store, due to its popularity, it is expected to sell out by the evening.

The event also features a variety of other collaboration products, such as the "Seafood Cream Croquette" from Kohakudo x Hokuyo Shokudo, the "Leaf Pie" from Juchheim x Yamamoto Nori Store, and the "Tokachi Daimyo Oyaki Chocolate Cookie & Cream" from Tokachi Daimyo x Loisdale, and stores have been bustling with activity since the first day.
