Jayasekara will launch the as-yet-unnamed restaurant in partnership with art dealer Tim Jefferies, who runs Hamiltons Gallery in Mayfair.
The pair have secured a 3,000 sq ft site, set over four floors, within the historic Bruton Place Mews building.
They have also secured another 800 sq ft site opposite the restaurant at 38 Bruton Place, which is set to become a delicatessen with takeaway option at ground floor level.
Both sites will be extensively remodelled before opening, with the restaurant expected to launch in the early autumn.
“It’s been a bit of a roller coaster the past couple of years with Covid, but we’re thrilled to have exchanged on this particular site,” says Jayasekara.
“When we first decided to open a restaurant together, we knew it would have to be in the right location, and this was our first choice.”
Jayasekara arrived in the UK in 2002 from his native Sri Lanka.
His early career saw him work at the three Michelin-starred Waterside Inn as chef de partie; Michel Bras in Route de Laguiole; and Le Manoir aux Quat’Saisons.
In 2015 he joined Gordon Ramsay's Pétrus as senior sous chef. In 2016, he won the Craft Guild National Chef of the Year Award, and was promoted to head chef at Pétrus shortly after.
He left the restaurant in 2018.
Jayasekara and Jefferies were advised by Dean Gambles & Co and Astrea by Hanover Green Retail.
“We are very excited to welcome Larry and Tim to Bruton Place,” says Tim Weston, asset management director at Astrea.
“Delivering the site has required significant collaboration from both sides, and it has been a pleasure working with the tenant team.
“The restaurant and delicatessen will add significant further amenity as part of our wider re-positioning of Bruton Place.”
