Split across two floors at No.5 Savile Row, the restaurant is set to be Jason and wife Irha’s personal and professional legacy and the pinnacle of culinary mastery. It marks a first for Savile Row - on which there has never been a restaurant leased in its 290-year-old history.

The venture sees a continuation of its sister restaurant Row on 45, which was awarded two Michelin stars within the first six months of its opening. Row on 5 is offering a world class 15-course tasting menu divided into three acts and showcasing the peak seasons of the finest of British produce.

Atherton said: “I have been fortunate enough to open restaurants all over the world, but Row on 5 is different. I want it to be my legacy, and I don’t say that lightly. ‘Row’ stands for ‘Refinement of Work’, and in this case I mean my life’s work as a chef.

“Row on 5 will be like a fashion designer’s haute couture collection - a showcase of creativity and finesse, but instead of fine fabrics and artisanal needlework, the stars of Row on 5 will be the world-class culinary team and the very best produce from all over the British Isles.”

At its helm is executive chef Spencer Metzger, formerly head chef at The Ritz for 13 years before he moved to Dubai as one of Jason’s opening chefs at Row on 45, and Roxane Dupuy as executive sommelier. The restaurant features just 28 covers.
