Woolf & Bird has closed its only site, on Exchange Street in Norwich, less than one year after it opened.

The concept, which was centred on locally reared free-range chicken, served five different ways, had previously operated as a pop-up before finding its first permanent site in February last year.

Announcing the news on its Facebook page, founder and chef Francis Woolf said it was “with a heavy heart” that the site would be closing.

“When we took on the large site at Exchange Street, we only saw big things, but existing as an independent, ethical, fast-food chain in such a large space was not sustainable,” he wrote.

“We found ourselves competing with chain restaurants, whose corporate structure and funding mean they can weather the tough times, whilst some independent outlets suffer and die. Sadly we have become a casualty of this,” he continued.

Woolf also opened café/restaurant Woolf & Social in the city’s Nelson Street, in 2016. He confirmed that this was still trading and “continues to grow ever better”.
