The contract will see the opening of two new cafés, as well as the ability to provide events catering.
Both cafés are set to open next summer as part of the re-development of IWM London. Open daily during museum hours, the first café will seat 144, and will have an outdoor seasonal terrace area seating a further 92, looking out on to the Geraldine Mary Harmsworth Park.
The second café will be situated on the first floor of the museum, directly off the new terraced galleries.
The menu is thought to mirror that of Peyton and Byrne’s other cafés, including own-brand sandwiches such as mozzarella, plum tomato and basil on focaccia, and pies including chicken and sweetcorn.
Oliver Peyton, founder and chairman of Peyton and Byrne, said: “Working with IWM and Foster + Partners is a privilege – the significant historical environment is inspiring, and we are excited about the opportunity to collaborate on a completely new way of looking at the visitor experience with the museum team.”
Diane Lees, director-general of IWM, commented: “One of the driving factors in our redevelopment was to improve the experience for our visitors, and we are delighted that Peyton and Byrne have come on board, to join us on this journey and run our brand new cafés.”
Founded in 2005, Peyton and Byrne runs several bakeries and cafés, located at The British Library, St Pancras Station, The Wellcome Collection, Central St Giles, and Wellington Street in Covent Garden, opened in September this year.
The company plans to open up to a dozen new bakeries in the next year, including sites in Chiswick and Brighton.
