Nonsense won the business after a five-way pitch against undisclosed agencies. The agency will be initially devising a social media strategy for the brand, before creating digital creative campaigns.
GBK is hoping its increased focus on digital marketing will help it drive long-term customer loyalty, for which until now it has depended on vouchers.
GBK was founded in 2001 and now has 55 restaurants in the UK.
Nonsense’s other clients include Cancer Research UK and the Science Museum.
