Derek Quelch, executive chef at London's Goring hotel, is set to leave the property after 15 years later this week.
Quelch, who oversees the entire food and beverage operation at the 69-bedroom hotel, is planning to take some time out with his family before making a decision on his future plans.
"I am very sad to be leaving the Goring but after 15 years I feel that it's time for a new challenge, whatever that might be," he said.
Quelch joined the Goring from Claridge's where he was executive sous chef under John Williams, now executive chef at the Ritz.
During his tenure at the Goring he has overseen a number of high-profile events, including the hotel's centenary celebration, which he marked with a special menu entitled 100 Years of Glorious Goring Grub. The hotel also famously hosted the Middleton family ahead of the Royal Wedding in 2011.
Last year, the Dining Room at the Goring was named best hotel restaurant in the Hotel Cateys and this January it became the first hotel in London to be awarded a Royal Warrant by the Queen for Hospitality Services.
David Morgan-Hewitt, managing director of the Goring, said he was very sorry to see Quelch leave.
"He has helped take the Goring both backwards and forwards by pushing the Britishness idea way before it became a big trend. It is now very much part of our DNA," he said.
Quelch's remit included the Dining Room as well as the lounge bar and the hotel's four private dining rooms as well as room service. The Goring is now looking for a replacement for Quelch.
