Mayfair residents wondering what's happening over at the old Ruya site on Upper Grosvenor Street, next to Corrigan's, should know that they'll have a new restaurant on their doorstep in the new year. It was bought by the Thesleff Group, which is behind Los Mochis in Notting Hill, Sale e Pepe in Knightsbridge and the Juno and Luna omakase restaurants.
This will be a brand new Japanese restaurant for them, called MA/NA, which they say "combines contemporary style and traditional Japanese techniques". We don't know much about that menu yet, other than a few of the dishes: Scallop Dynamite Maki, Kani Tartare Salad and Bulgogi Robata.
In charge of the food here will be Executive Chef Leonard Tanyag (who also looks after the menus for Los Mochis, Juno and Luna) and Bar Director Pietro Collina (who looks after the drinks at Los Mochis and Sale e Pepe).
"This acquisition is more than just a new address — it’s a return," said Markus Thesleff. His first hospitality venture was the Mayfair club Pangaea, which was always a popular hangout of Prince Harry back in his pre-Megan days. “Mayfair has always been part of my story...With this new concept, we’re not seeking to redefine Mayfair - we’re simply bringing our flavour of hospitality to it."
