The experience offers an original immersion in Chef Etchebest's kitchens, in the basement of the Quatrième mur, opposite the brigades. The table d'hôtes concept works: direct interaction with the chefs, up-to-the-minute presentation of dishes, guest involvement in preparation. The welcome begins with a video call from the absent chef. The menu favors local producers with masterful creations. The "araignée de mer bretonne" (spider crab) from Brittany reveals an accomplished technique, playing with textures and carcass granite. The "Sous-bois" signature dish impresses with its copper-tube penne, mushroom fricassee with yellow wine and precise execution. Grilled lettuce celtuce is surprisingly worked like a piece of meat. Salmon with sorrel cleverly revisits Troisgros, perfectly cooked and reduced to the minute. Beef Wellington revisited seduces with its simplicity. The wine list, presented like a grimoire, covers all regions, with suggestions adapted to each dish. The sommelier gives judicious advice: IGP Collines Rhodaniennes 2023, Margaux Angludet 2016, a pertinent selection. The rhythmic service avoids waiting, and the balanced animation maintains interest without forcing it. The desserts, however, take a back seat, with their less assertive technique.
