Job Description

Assistant General Manager -- MA/NA (Opening January 2026)

Location:

30 Upper Grosvenor Street, Mayfair

Opening:

January 2026

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 detail -- from light and sound to service and design -- is intentional. Each element works in harmony to reveal the extraordinary within the simple.
