Senior Sommelier – MA/NA Opening in early 2026 on Upper Grosvenor Street, MA/NA is born from the Japanese philosophy that every ingredient carries an invisible power — a life-force shaped by nature and the hands that honour it. ‘Mana’ is the spiritual energy that exists beneath the surface of all things. It is felt rather than seen — transforming emotion into experience, and a meal into memory. Guided by this belief, MA/NA offers a seamless blend of restaurant and bar — refined Japanese dishes alongside an exceptional cocktail, wine, and sake list. Here, cocktails flow effortlessly into dinner, and dinner naturally returns to drinks. Every element — from design and service to sound and light — is intentional. Each detail celebrates the extraordinary within the simple.
