It follows the announcement that chef Nathan Outlaw, whose eponymous Cornwall restaurant holds two Michelin stars, is to open a separate brasserie-style restaurant at the hotel in late spring.
Cooper has overseen The Dining Room restaurant at The Goring since 2013 and it won its first Michelin star in 2016.
He has yet to announce his next role but will move on later in the year.
The Goring CEO Jeremy Goring praised Cooper as ‘one of the very best chefs in the country’ and hinted that the hotel had its sights on a second Michelin star.
“With [Cooper’s] help over the last five years we’ve taken The Dining Room to a new level,” he says.
“Now we intend to continue building on that and take another big step upwards in our flagship restaurant. Looking forward, there is a lot of excitement within The Goring as to what 2019 will bring.”
The Goring is looking to fill the executive chef vacancy at The Dining Room and says it is searching for a candidate with the ‘creativity and initiative to push the restaurant even further’.
Outlaw will open a separate restaurant at the hotel this year when his seven-year partnership with The Capital hotel in Knightsbridge comes to an end in March.
He launched Outlaw’s at The Capital in 2012 and it won a Michelin star soon after opening, but lost the accolade in the 2019 edition of the guide.
