Foodservice firm Amadeus has won a £5.4m contract with the Dudley Zoological Gardens (DZG).
The seven-year deal will run from 7 April and include catering and events management.
The events management aspect will focus primarily on the venue's 11th century castle, which Amadeus hopes to develop as a setting for weddings and functions.
The new Amadeus deal comes as part of an on-going, five-year, £1.2m investment programme into the 40-acre DZG.
Amadeus managing director, Kevin Watson, said: "We are pleased to add the Dudley Zoo catering contract to our growing portfolio of fixed site 'visit' venues. Dudley Zoo is undergoing significant investment and we have been tasked with improving the catering in line with the visitor experience. I have every confidence that we will raise standards of food and service whilst offering value for money."
DZG chief executive, Peter Suddock, said Amadeus's experience in catering for similar visitor attractions had helped ensure their successful selection.
Foodservice company Amadeus is one of the largest in the UK, and has contracts with major venues and sites, such as the NEC, a £5m deal with the London Borough of Camden, and Birmingham Town Hall.
It also recently announced a £7m, five-year deal with Cadbury World near Birmingham, which included a major revamp of the café and its menu.
