Restaurant group D&D London has struck a deal with industry investors which is designed to secure its future, according to reports this week.

The deal, which values the company at around £60million, involves Calveton, the owner of Byron hamburgers, and Breal Capital, which recently took over Vinoteca wine bars to add to the three brewers it acquired earlier this year.

The deal would see co-founder David Loewi remain as chief executive, and would provide the “patient” money required for future growth, rather than the immediate profits required of private equity funding.

Des Gunewardina, the other ‘D’ who founded the company from the former Conran restaurant operation in 2006, left earlier this year amid the upheavals that saw the closure of two London venues, Avenue and Radici, along with East 5th in Leeds and Klosterhaus in Bristol.

D&D has about 40 restaurants from London to New York and Paris, including Bluebird, Quaglino’s, Sartoria, Fiume and Launceston Place in London and 20 Stories in Manchester.

Calveton’s founder, Sandeep Vyas, said: “Our shared vision is to preserve the rich heritage and identities of these remarkable restaurants.“
