Gault&Millau's review 2026

At the entrance to the upper town of Langres, almost right up against the ramparts, the Clos Vauban exudes the quiet strength of houses that have lived through many eras. Originally an officers’ mess, the 1866 building has been reimagined by Laurent and Martine Petit without the stiffness often associated with historic preservation or ostentatious luxury. You walk through a striking wicker tunnel before discovering the Bulle d’Osier: just six tables, woven alcoves, bouquets from the garden, and that rare sensation of stepping not into a stage set but into a lived-in home. Valentin Loison’s cuisine is described as “farm-to-table and foraged”: the phrase might seem contrived were it not backed by a 2,000-square-meter vegetable garden, wild foraging, and close relationships with producers in the Haute-Marne region. Here, the terroir is not just rhetoric: it is embodied in living ingredients—sometimes fermented, aged, roasted, or concentrated—to reveal unexpected flavors. The trout, prepared like hamachi, captivates with the elegance of its presentation and a remarkable fermented strawberry juice—even if the intensity of the latter ultimately pushes the fish into the background. The crayfish, barely seared, find a spicy, garlicky depth in an XO sauce prepared with their heads and shells, executed with Japanese precision. The long-aged shallot, surrounded by caramelized onions, licorice, vinegar, and hazelnuts, yields a soup of exceptional intensity—arguably one of the highlights of the meal. The Rhône pikeperch, firmed up by about ten days of aging, achieves superb balance under a whipped butter sauce with sudachi, fish roe, and lemon caviar—a generous sauce that celery and lovage keep in perfect balance. The lamb, prepared in several cuts, is refreshed by wild garlic, tarragon, and mint. Finally, fermented endive roots and Milky Oolong tea come together in a bold dessert, where bitterness, flakiness, and caramelized notes interact without ever disrupting the harmony. The service, led with precision and conviction by Anaïs Bercegeay, complements this unpretentious cuisine, while the wine cellar—brilliant in its selection of Burgundies, Champagnes, and Loire wines—showcases a strong preference for artisan winemakers and minimally interventionist wines. Our only regret is that the menu remains hidden: the program is handed out only after the meal is over, when we would have liked to play a more active role in selecting our dishes.
