Sablon, who won the 2007 Roux Scholarship, will depart on 18 February with Marcus Klumb replacing him as executive chef.
During his tenure Sablon oversaw the opening of Laurent Tourondel’s Laurent restaurant and Albert Adria’s Cakes & Bubbles at the hotel in 2018.
Klumb began his career in London at Helene Darroze at The Connaught in 2007, working as commis and then junior sous chef.
After a brief time at One Aldwych he joined Shangri-La at The Shard, working as senior sous chef and then chef de cuisine, before being appointed executive sous chef at Four Seasons Ten Trinity Square ahead of its opening in 2017.
“I am delighted to be joining Hotel Café Royal as executive chef this month, and look forward to bringing my experience to such a revered establishment,” says Klumb.
Sablon has yet to announce his future plans.
