With around 1,500 employees, the store will have the same price as its other high-street stores, however there will be discounts for building occupants.
Shane Kavanagh, CEO of Crussh said: “We are really excited by this opportunity to step into the world of workplace catering and help promote wellbeing and healthy living at the Minster building.
“We’ve been impressed by the landlord’s commitment to delivering a unique building since we first met them, and we look forward to meeting the building tenants and introducing them to our brand.”
Minster Building's landlord is Ivanhoe Cambridge, and it worked with developer Greycoat on the space and design for the multi-tenant building, which has recently been renovated to create up to 230,000 sq ft of flexible office space.
It will operate a WiFi enabled café space on the Ground Floor with access for the public.
The new Crussh workplace format will stay true to the Crussh fit food and juice bars classic menu, offering freshly made juices and smoothies as well as a large range of healthy food from breakfast pots and bagels to salads, wraps and healthy treats.
Organic and Fairtrade coffee will form the core of the offer and will be handmade.
