MA/NA Mayfair: London's New Japanese Restaurant Blends Luxury with Warmth

A new Japanese dining establishment, MA/NA Mayfair, has launched in the affluent Mayfair area of London, operated by the Thesleff Group, which is also behind Los Mochis, Juno, Luna Omakase, and Sale e Pepe. Situated at 30 Upper Grosvenor St, close to Hyde Park, the venue showcases a design by OV&CO from Los Angeles, featuring earthy browns and golds inspired by Kyoto’s autumn and the vibrancy of Tokyo nights. The space includes a lounge, bar, main dining area with a unique Magma lighting piece by EWE Studio, and a private room for 20. Executive chef Leo Tanyag curates a gluten-free menu with dishes like O-Toro Tartare and A5 Wagyu Ishiyaki steaks. MA/NA is among the select few in London authorized to serve Kobe beef from Hyōgo Prefecture's Tajima strain. Bar director Pietro Collina, previously with Nomad, Side Hustle, and Eleven Madison Park, manages the drink offerings. The restaurant's name reflects the Japanese concept of 'mana,' highlighting the essence of its ingredients.
