Assistant Head Sommelier — MA/NA (Opening January 2026)
Location: 30 Upper Grosvenor Street, Mayfair
About MA/NA
Opening in January 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.
The Role - Assistant Head Sommelier
As Assistant Head Sommelier at MA/NA, you will support the creation and execution of an exceptional beverage programme that celebrates the harmony between wine, sake, and Japanese cuisine.
Working closely with the Head Sommelier, you will help develop and maintain a world-class cellar - one that reflects refinement, discovery, and respect for craftsmanship. You’ll guide guests and team members through a journey of flavour and philosophy, connecting them to the story and energy behind each bottle.
Collaborating across the kitchen and bar teams, you’ll help ensure perfect synergy between dishes, cocktails, and pairings, elevating every aspect of the guest experience.
This is a dynamic, hands-on role suited to a Sommelier who embodies curiosity, precision, and emotional intelligence - someone who strives to learn, lead, and grow within a world-class opening.
