The Genuine Dining Co has secured a three-year deal with office concept firm Spaces in London which is expected to generate £1.6m in total turnover.
The contract will see the catering company run a new café at the London office for Spaces in the newly refurbished Mappin House on Oxford Street.
The London building can hold up to 500 people, not including the private membership business club.
Chris Mitchell, managing director at the Genuine Dining Co said: "This win is an exciting contract for Genuine Dining Co and we are very much enjoying working with a cool like-minded company."
Everything on the café's menu will be made from fresh produce ranging from Southampton based single origin barista coffee to sandwiches, salads and smoothies.
The catering firm delivers food to a variety of businesses across the UK including film studios, law firms and banks.
