MA/NA opened on 27 April 2026 at 30 Upper Grosvenor Street, Markus Thesleff’s Mayfair Japanese after Los Mochis, Sale e Pepe and Luna Omakase. Condé Nast Traveller filed the June room: small plates, robata, sushi, Japanese A5 wagyu on a hot Himalayan salt stone. Monday to Saturday until 1:30am.
The little-known fact is the clock: this is a drinking destination that happens to cook, not a tasting-menu temple that happens to pour, so the late sitting is the point. Wallpaper* walked other 2026 rooms the same summer; CNT sat MA/NA among them. @mana.mayfair is the live camera.
The robata is why you go; Upper Grosvenor Street is why it feels like London.
