M&S is to test Wasabi counters in its foodhalls in an effort to improve its in-store experience and fresh food offer.
M&S will begin the trial at five of its stores, four of which will be in London, with all to open before Christmas.
The Wasabi counters will serve both freshly prepared sushi and hot food with customers ordering at the Wasabi counter and paying at the M&S counter to encourage purchases across both brands.
M&S food director Andy Adcock said: “This partnership will see us bring new products and a new experience to our customers.
“Health, convenience and food on the move are all growing areas of our business and by working with an expert partner we know we can offer our customers the very best.”
M&S is one of several grocery retailers adding food counters to stores.
Eateries are one way that grocers and department stores are using up excess space. Food counters have the added advantage of both driving footfall and encouraging customers to make purchases across several brands.
