The firm, who has provided catering services for the gallery’s restaurants, cafés and dining rooms for the last nine years, has agreed a deal worth an estimated £36m.
Peyton and Byrne founder Oliver Peyton said: “Following nine years’ experience, Peyton and Byrne are perfectly placed to continue enhancing the service and food standards at this iconic venue and as such we have big plans to evolve the current restaurant and café concepts.
“The National Gallery is one of the greatest museums in the world and it is critical that the dining experience is world class too.”
Douglas Gilmore, trading director of National Gallery Company Ltd. added: “We have ambitious plans to enhance the public catering offer at The National Gallery and believe our well established relationship with Peyton and Byrne, who understand our visitor requirements, will be a significant factor in helping us realise these plans”.
Peyton and Byrne first took over the National Gallery contract in 2005. The company also provides services to other venues including The Royal Academy, The Wallace Collection and The Royal Botanic Gardens Kew.
