One Saturday afternoon last month, six second graders from P.S. 295 in Brooklyn got a head start on the fine-dining life when they visited the acclaimed French restaurant Daniel. There, five waiters presented them with a seven-course tasting menu (after the trio of canapés and an amuse-bouche, naturellement). The meal was overseen by the star chef and eponym himself, Daniel Boulud, whose goal was, he says, “for the children to really discover a lot of flavor, a lot of layers, a lot of texture.”
