The restaurant, the creation of Azurmendi Bilbao head chef Eneko Atxa and One Aldwych Hotel's general manager Kostas Sfaltos, will open next summer in the space formerly occupied by the hotel's restaurant Axis.
Work will start to transform the area within the Covent Garden-based hotel early next year with plans to Eneko At One Aldwych next summer where the three Michelin-star chef will serve his 'inventive interpretation of traditional Basque country cuisine'.
Sfaltos said although it would have high standards, the restaurant would aim to offer a relaxed dining experience.
“Eneko has incredible vision and passion for Basque cuisine and shares the same standards of quality, quest for innovation and respect for traditions as we do," he said.
Atxa, whose restaurant in Bilbao is also ranked number 19 on the World's 50 Best Restaurants list, said: "We aim to create an unpretentious modern take on rustic Basque cuisine, based on quality ingredients, simplicity and culinary heritage. One Aldwych Hotel is the perfect partner for this joint creation”.
The 105-bedroom One Aldwych Hotel, a member of Leading Hotels of the World, opened in 1998 and also houses Indigo restaurant which is headed up by chef Dominic Teague.
