Chef Mark Jarvis has parted ways with Mayfair's Neo-Bistro after acting as a consultant since its opening in June 2017.
Jarvis, who owns Anglo in Farringdon and Stem in Mayfair, had advised the restaurant on menus and kitchen operations.
The winner of the Newcomer Award at the 2017 Cateys will continue to work full-time in the kitchen at Anglo and collaborate with head chef Sam Ashton-Booth at Stem.
Jarvis had opened Neo-Bistro in partnership with Alex Harper, former head chef of Fulham's Harwood Arms.
He has said the management and staff of the restaurant will continue to operate it until further notice.
Jarvis started working in kitchens at the age of 16 and cooked at the Lords of the Manor in the Cotswolds before joining Belmond Le Manoir aux Quat'Saisons in Great Milton, Oxfordshire and going on to open Blanc's pub, the Thatch.
After eight months at the Thatch, Jarvis went on to work at the Royal Exchange London, as senior chef de partie before joining Michelin-starred Texture in London, holding the position of sous chef for two years. His first head chef role was at the Blueprint Café, where he took over from Jeremy Lee. A year later, Jarvis took on his first executive chef role at the Bingham hotel in Surrey, where he remained for two years.
