Creativevents, Mitie's specialist outdoor catering business, has been awarded the contract for all hospitality at the RHS Hampton Court Palace Garden Festival in July.
Creativevents was chosen to provide luxury restaurants, three à la carte restaurants, two delicatessens and a traditional afternoon tea area.
The event expects to receive 140,000 visitors from 1-7 July over the 34-acre site in Richmond upon Thames.
The company will introduce menus designed by culinary experts Jose Pizarro and Ramael Scully, who are part of The Gathered Table collaboration.
Pizarro, known as the Godfather of Spanish cooking in the UK, has created Tapas on the Terrace for the festival within the Dig In restaurant marquee. It will offer a selection of traditional and innovative Spanish delicacies, with champagne and cocktails.
Scully, formerly head chef at Yotam Ottolenghi's NOPI, has recently opened Scully St James's.
For Creativevents, he has designed Scully's Deli, which will offer sandwiches, paninis and cakes. There will also be a gin bar with a jazz band playing in the afternoons.
There will be an opportunity for visitors to experience a 1950s-style traditional afternoon tea in the Festival of Roses area. Afternoon Tea includes traditional cucumber sandwiches, scones with Cornish clotted cream and caramel eclairs. Customers opting for high tea can also enjoy a glass of champagne.
