Chef Dan Kenny is to close his Brighton restaurant the Set in March 2021 after nearly six years of trading.
Announcing the news on Instagram, Kenny said he hoped the restaurant will "live on" in another guise.
The Set was launched by Kenny and chef Semone Bonner within the Artist Residence hotel on Brighton's Regency Square in 2015.
It was awarded a Michelin Bib Gourmand, given to restaurants offering ‘good quality, good value' cooking with a menu of three courses for £28 or under, in the Michelin Guide for Great Britain and Ireland 2020.
Kenny wrote on Instagram: "After almost six years residing and working alongside Artist Residence this chapter is coming to an end. We will be leaving our residence at the hotel on 31 March 2021. We want to close the chapter by putting out the best food we have ever cooked, so please do book in to come and say goodbye with a final meal with us.
"There are too many people to mention but you know who you are are. Again a huge thanks; your help, support and compassion has fuelled the restaurant and made it something we are proud of.
"We hope the Set will live on. The new year may bring us a new home, or we may look at new projects such as pop-ups, exclusive private dining and some other stuff (once we think of it). We shall keep you posted."
Kenny took over the entire food and beverage operation at the Artist Residence hotel in 2018..
Coronavirus restrictions forced the hotel's the Fix cocktail bar to permanently close in July this year.
