Waitrose's OOH campaign by Wonderhood Studios creatively showcases the versatility of kebabs with a playful and eye-catching billboard. The ad features a large skewer piercing various food items, reinforcing the humorous message that 'Anything is a kebab if you put a skewer through it.' This approach not only grabs attention but also cleverly positions kebabs as a fun and flexible summer food option, appealing to a broad audience.
