McDonald’s Brazil has brought McFish (Filet-o-Fish) back to its menu nationwide, this time built around a campaign that takes the sandwich’s return on a deep-sea expedition to the mythical city of Atlantis. Created by GALERIA.ag, “McFish and the Lost Recipe of Atlantis” builds on previous seasons’ storytelling — which once traced the pollock fillet’s origins to Alaska — with a new narrative arc and the launch of McFish Deluxe, made with lettuce and tomato.
Ahead of the campaign’s launch, Méqui engaged fans through a narrative-driven content series on social media, designed to build anticipation and nostalgia around McFish’s return. The film follows a group of “Fish Lovers” on an archaeological expedition beneath the sea, leading them to Atlantis and its lost recipe, along with an ancient version of “Méqui 1000,” the brand’s iconic restaurant on Avenida Paulista, and traces of Atlantean civilization.
In “McFish and the Lost Recipe of Atlantis,” audiences finally see the journey that brought the sandwich back. With McFish off the menu, the Fish Lovers journeyed deep beneath the sea on an archaeological expedition that led them to Atlantis and its lost recipe. Along the way, they uncovered an ancient version of “Méqui 1000,” the iconic McDonald’s restaurant on Avenida Paulista, along with mysterious murals and traces of Atlantean civilization. The brand has now brought its greatest discovery to the menu: McFish Deluxe, made with lettuce and tomato.
The film was inspired by the visual language of director Wes Anderson, with a scale model of Atlantis built to give the concept a tangible form.
The expedition theme also reaches Avenida Paulista, where Méqui 1000 will unveil a new façade and interior inspired by Atlantis starting this week. Created by GALERIA, the campaign includes a TV commercial, digital strategy, out-of-home media, content and influencer activations, an exclusive launch event, and a series of brand experiences.
The sandwiches will be available for a limited time or while supplies last at McDonald’s restaurants across Brazil. Follow Méqui’s latest updates on its site or official social media accounts.
