French chef Eric Chavot is leaving the two-Michelin-starred restaurant at the Capital hotel in London.
The surprise move sees Chavot leave the restaurant in Knightsbridge after more than a decade behind the stove. He will leave on 15 August.
His departure is one of a series of recent staff changes at David Levin's Capital and Levin hotels including general manager Henrik Muehle, who left to join the St James's Hotel and Club in Mayfair last month.
The Capital's restaurant manager, Christoph Thuilat, is also leaving to join Muehle and become food and beverage manager at the St James.
Last year, Levin's son Joe left his long-serving role as managing director at the Capital Group.
Chavot said he made the decision to leave the Capital, where he has held two Michelin stars for eight years, to change his life.
"I am leaving after ten years and my departure is amicable," he said.
"I have done everything I can at the Capital and it's been great. But I feel the time has come for me to do something different with my life. I've been doing Michelin cooking for so long and I'm not sure I want to do this anymore.
"I have no idea what I am going to do or where I am going to go. Some people may call me crazy to do this in a recession but you only live once and now is as good a time as any."
Chavot added that after his departure in August he will take time off to go on a culinary tour of England.
