D&D London is to close four of its UK restaurants this month in the face of "economic challenges"
The group confirmed East 59th in Leeds, Avenue and Radici in London, and Klosterhaus in Bristol will all cease trading in early January.
It follows a report last year that multiple D&D restaurants were up for sale, and the group said at the time that it was reviewing its portfolio.
A D&D spokesperson said: "Like many other businesses in the hospitality sector, we continue to strategically review our portfolio and such decision is a result of the current economic challenges including spiralling utility, food and beverage costs and the unstable labour market.
"D&D London intend to look after the restaurants’ greatly valued staff and management and wherever possible will seek to offer exciting positions in our other venues."
Klosterhaus, which was based in Bristol's Cabot Circus, has closed its doors after just over two years of trading.
The restaurant opened in October 2020 and was designed to pay tribute to the "dining scene of grand mittel-European cafés".
The menu offered dishes such as soused herring with herring caviar; and chicken and veal schnitzels.
The two-storey 18th-century venue featured a restaurant, bar, and terrace, as well as spacious areas for business meetings and social events.
A statement released on Klosterhaus’s website said: "Dear friends, please note that Klosterhaus has now closed, however we would be delighted to welcome you at one of our sister restaurants."
D&D said its wider portfolio of around 40 restaurants continued to trade well despite strike action affecting transport in December and that its Birmingham site Orelle, which launched in October, had exceeded revenue projections.
It was reported in 2022 that Interpath Advisory had been appointed to launch a sale process for D&D London, which is estimated to be worth around £100m.
