In his new role Pitfield will be responsible for overseeing all of the company’s six UK restaurants and new launches.
Hakkasan Group’s acting chief executive Didier Souillat said: "We are thrilled to welcome Duncan to the company and look forward to working with him during this exciting time of growth for the company. His passion for employing and developing talented professionals within the hospitality industry will help to further develop and strengthen our company’s high standards.”
Pitfield started with D&D London as general manager at The Royal Exchange. He went on to open Restaurant Sauterelle and Skylon before becoming senior general manager, which saw him hold responsibility for restaurants including the Blueprint Café, Le Pont de la Tour and the Old Bengal Warehouse.
