Marks & Spencer will open a new-format standalone sandwich shop in London this spring, called M&S To Go.

The store will stock a range of pre-packed sandwiches, fresh baguettes and a limited selection of hot food, such as soups and porridge. The 700 sq ft store will sit next door to M&S’s full-line department store on trendy Kensington High Street.

An M&S spokeswoman said: “This site came up and it gave us a chance to extend our presence in this location, but there are no plans to roll out the concept.”

M&S To Go is an extension of the retailer’s Food To Go offer, which it features in 17 of its department stores. The spokeswoman said that, 99 per cent of the time, the food offer will be within the footprint of the department store.

M&S has experimented with other eatery concepts in the past including M&S Kitchen, which opened in Canterbury in November 2006. The store features its Eat Over Deli and Hot Food To Go offers.
