The Gordon Ramsay Group has confirmed Maria Tampakis as head chef for the Heddon Street Kitchen, and confirmed that the site will open the week beginning 10 November.
Tampakis was formerly senior sous chef at the St Paul's site Bread Street Kitchen, and also worked at the three-Michelin-starred Jean-Georges restaurant in New York.
The new all-day venue will be the group's 13th London site, and have 232 covers across three floors, spanning 8,900 sq ft, with an open kitchen and pass. It will serve breakfast, lunch and dinner, seven days a week, and hopes to appeal to both locals and tourists.
Previously a Living Room bar and restaurant, the site has now been renovated by Russell Sage Studios to also include an ice cream bar, a wine tasting counter, a raw bar, a cocktail lounge area, and a private room.
Managing director Stuart Gillies said: "We are extremely excited to be opening in the very heart of the West End. We have developed Heddon Street Kitchen as an accessible all-day concept."
The Gordon Ramsay Group is a group of restaurants and bars by the celebrity chef and restaurateur. It currently runs 12 venues across London, employing over 700 people in total, including three-Michelin-starred flagship Restaurant Gordon Ramsay, by Clare Smyth.
It also has sites across the world, including Bread Street Kitchen Hong Kong, and Gordon Ramsay Steak in Las Vegas.
