Caterer Graysons has been awarded a £4 million-a-year contract to cater for the British Library at St Pancras, London, from October.
The contract runs for five years and will see Graysons work in partnership with the library to manage public restaurant and cafés at the grade I listed building on the Euston Road.
In addition, it will carry out event catering and hospitality services for the British Library Conference Centre, manage staff catering facilities, and assist the library to constantly develop its food and drink services - including a new members' lounge and bar area.
The award is Graysons' second major contract in the Knowledge Quarter around St Pancras - last year the company was chosen as caterer to the neighbouring Francis Crick Institute.
Graysons is already planning with the British Library team to refurbish all the public catering areas in early 2017. This will see Graysons invest in the areas and create a new café area.
Caroline Brown, head of commercial services at the British Library, said: "Graysons impressed us throughout the tender process with their approach to building strong partnerships and their commitment to tailoring their offer and service. We are currently engaged in a series of projects at the British Library which will transform the way people experience and enjoy our buildings."
