Sainsbury’s has opened its first sandwich shop this morning in Fleet Street, nearby to its Holborn head office.

The store sells hot and cold food to go, and is similar in style to established chains such as Pret A Manger and Eat.

It is not yet clear if the trial store will be rolled out to other locations.

Sainsbury’s yesterday reported a record Christmas with like-for-like sales for its third quarter up 3.6%. The grocer has emerged the winner out of the big four supermarkets.
