Assistant Restaurant Manager — MA/NA
Location: 30 Upper Grosvenor Street, Mayfair
About 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.
The Role — Assistant Restaurant Manager
As Assistant Restaurant Manager at MA/NA, you will support the Restaurant Manager in leading the front-of-house team and delivering an experience defined by harmony, precision, and warmth.
You will play a key role in the daily rhythm of service, ensuring that every guest journey — from arrival to farewell — flows effortlessly. Working closely with the kitchen, bar, and sommelier teams, you’ll help cultivate a sense of unity and purpose across all aspects of the restaurant.
You will lead by example on the floor, demonstrating grace, emotional intelligence, and attention to detail — supporting the team to perform with calm confidence and genuine hospitality.
This is a role for a hospitality professional who understands that exceptional service is not only seen, but felt — and who is eager to grow within a flagship opening.
