James Robson, owner and managing director of the New Bond Street venue, founded the business in 2006 but told BigHospitality he had decided to make the change to keep ahead of the restaurant market and to recognise current trends in dining.
"We decided the market was changing and therefore updated the restaurant to give Londoners a new take on the best of British without any pomp and so delivered Mews of Mayfair British Brasserie," he said.
The 65-cover brasserie is located on the first floor of the venue and has recently undergone a full refurb to reflect the menu which showcases British produce - local linens, oak tables and worn leather chairs sit alongside rustic plates and cups which have been specially sourced.
As well as the main dining space, there is an outside area which can cater for 60 people as well as a top floor chef's dining room for private dining or events and the Mews of Mayfair bar, lounge and private dining and tasting room - La Cave.
As part of the relaunch, the team have appointed chef Jamie Hibbert to head up the brigade in the kitchen. He has helped design a menu which Robson says is now focused around the new British theme.
"Mews of Mayfair’s British Brasserie will now deliver quality British dishes in relaxed surroundings that all have the British stamp. The interiors have been designed by Goose Design Interiors. The menu includes classic British cuisine made using the finest British ingredients.
"The brasserie serves up a range of British classics such as Gressingham duck breast, Cornish hake, Herdwick lamb and Galloway beef from The Yorkshire Game Company," Robson added.
With a price point of around £20 for a main, menu highlights include salt-baked Goosnargh chicken and banoffee pie - both served as sharing dishes for two.
The Mews of Mayfair relaunch comes not long after the opening of a fellow British-themed restaurant in Mayfair - The GrEAT British Restaurant - last month.
