Chef Ollie Couillaud is leaving the Dorchester after only a year to take up the role as head chef at Tom Aiken's second London restaurant, Tom's Kitchen.
Couillard left Chiswick's three-AA-rosette La Trompette last May to take up the post of head chef the Dorchester's Grill Room.
He will now take up the reins at Tom's Kitchen, which opens in the former Blenheim pub on Cale Street, Chelsea, in September.
