Which Wich, the US sandwich chain, is expanding its UK operations with the launch of two new dark kitchens, in Battersea and Bethnal Green.

The build-you-own sub brand launched in Covent Garden’s Central St Giles development in early 2018 with plans to open a further 10 locations in the capital.

Which Wich says it had planned to launch a brace of City of London locations but that the pandemic has caused it to adjust its ‘short-term expansion plans’.

“In a challenging time for the London hospitality market, we are delighted to have the proven track record to launch new openings, bringing renewed menu choice to London customers and new jobs for talented team members,” master franchisee Rami Awad said.

Founded in Dallas, Texas, in 2003, the company operates 500 restaurants in 10 countries.

The Subway-style assembly-line approach allows customers to choose from a set menu or customise their sandwiches by ticking off the toppings.
