The group, which also owns the Yangtze brand, launched in 2004 and now has more than 40 company-owned sites across the UK, plus several franchise units.
It received £2m from Metro Bank last year to add to its growing number of noodle bars in shopping centres, high streets and travel hubs.
“Chopstix is in a good place to further grow over the coming few years and cement its place as the UK’s leading Asian QSR brand,” says Chopstix managing director Jon Lake.
Since January the company has opened sites under its core brand in Intu Nottingham, Birmingham, Bristol Cribbs Causeway, Glasgow, Earls Court and Southampton’s West Quay scheme.
Chopstix is also undergoing changes to its senior team with Mark Carrick, formerly of Comptoir Group, joining the company in October as finance director.
He replaces Michael Toon, who is leaving to join burger brand Byron.
