It followed a competitive pitch, the agency said on its Facebook page.
"The PR programme will be a packed one, featuring several set-piece activations alongside a hefty dollop of Michelin-starred media relations," it added.
"Alongside a focus on promoting the 2015 event, which takes place on 17-21 June in London’s Regents Park, our remit will include positioning Taste Festivals as the world’s leading food and drink event organisation. Taste of London is the definitive showcase of London’s best restaurants and the world’s most prominent chefs. The festival also provides a unique platform to promote a diverse and exciting range of premium food and drink."
The agency officially launched last month. Its first client was VITL, the health supplement supplier.
