The 2-AA-Rosette dining room is shut for four weeks and will reopen with art deco-inspired interiors and a new brass and quartz bar stocking a range of champagnes, spirits and cocktails.
The five-star Cheshire hotel is also home to Simon Radley at The Chester Grosvenor, which has held a Michelin star since 1990.
The relaunched La Brasserie will offer a new menu developed by Radley and his brigade.
Richard Grove, general manager of The Chester Grosvenor, says the hotel saw a ‘gap in the market’ for a ‘luxurious’ bar in the city.
"We believe that our new plans will go above and beyond people’s expectations and we are more than excited to re-open our doors to not only our existing and loyal guests, but new ones too," says Grove.
“We’ve had these plans in the pipeline for quite a while so it’s great to see them finally coming to fruition. 2018 is going to be a very exciting year indeed."
La Brasserie is scheduled to reopen on 1 February.
