The alchemists in Bertrand Grébaut's Michelin-starred kitchen produce truly beautiful creations, served by blue-aproned waitstaff. The menu reads like an obscure shopping list: each dish is a mere listing of three ingredients, while the mystery dinner puts you in the hands of the innovative chef. Reservations require planning and perseverance – book at least three weeks in advance. Its nearby wine bar is ideal for a pre- or post-meal drink. For stunning seafood tapas, its sister restaurant is right next door.
