The opening marks a return to the area for Atherton, who previously launched the Maze restaurant on Grosvenor Square in 2005. The Biltmore, Mayfair will also become Europe’s first property within the LXR Hotels and Resorts collection.
The Betterment’s head chef will be Paul Walsh, who launched and led Jason Atherton’s City Social for five years and achieved the restaurant’s Michelin-starred status within seven months of its opening.
The Betterment’s seasonally driven menu will feature dishes of wood-fired fish and meats, fresh seafood, signature salads and plant-based plates. At the heart of the restaurant will be an open grill centrepiece.
This new restaurant and lifestyle offering, located at The Biltmore, Mayfair, will also include The Terrace, The Tea Lounge and The Pine Bar, all overseen by Jason Atherton.
Atherton said: “To be working on the launch of The Betterment at The Biltmore, Mayfair is incredibly exciting. When we were approached by Mr Kwek, Chairman of Millennium & Copthorne Hotels plc, owner of The Biltmore, Mayfair, we just knew it was an opportunity we couldn’t let pass.
“We chose the name The Betterment to encapsulate our journey from opening Pollen Street Social in 2011 to today, highlighting the progression of our food, ethos and way of thinking. To be returning to Mayfair’s Grosvenor Square after nine years is very special to me, and I’m thrilled to be doing it alongside world-class chef and friend, Paul Walsh.”
The Biltmore, Mayfair, formerly the Millennium Mayfair, is undergoing a £60m redevelopment to become Europe’s first property within the collection and will feature 308 rooms and 58 curated suites.
