H3, a "not so" fast food franchise in Portugal, has launched a burger featuring the traditional francesinha sauce. The francesinha is a dish over which every Portuguese seems to have an opinion, yet few ever agree on which is the best. The “Francesinha Burger” is sure to heat up the debate.

To mark this launch, H3 challenged some of Portugal’s most renowned francesinha restaurants by placing playful posters referencing their names in front of their doors. With the slogan “This One Will Bring the Sauce,” the campaign reignites the ongoing conversation about the country’s favorite francesinha.

The campaign also comes to life on social media, with videos, vox pops, challenges, giveaways, and other interactive activities. By engaging some of Portugals’s most iconic restaurants, H3 sparks discussion and excitement around this beloved local dish.
