The restaurant, which launched four years ago in Granary Square, will close its doors on 23 August.
Loubet is keen to move away from full-time cooking after a career that has spanned more than 40 years. The Bordeaux-born chef has worked at La Tante Claire under Pierre Koffmann and also at Le Manoir Aux Quat’Saisons and has run London restaurants including Bistrot Bruno, in Soho, L’Odeon on Regent Street, and Bistrot Bruno Loubet in The Zetter Hotel in Clerkenwell.
At Grain Store he put vegetables to the forefront of the menu and championed sustainable practises.
Michael Benyan and Mark Sainsbury, the pair behind The Zetter Group of hotels and business partners with Loubet, say they are closing the restaurant because they don’t feel it would be possible to run it without the chef at the helm. They have accepted an offer on the site, although it is not yet known what will replace it.
Grain Store Gatwick, an offshoot of the restaurant that launched in the airport in early 2016, remains open and Loubet will continue to work with Airport Retail Enterprises on the restaurant project.
