Burger King has become famous for its stunts. It’s most incisive are the pranks that draw rival, McDonald’s, into its web of humour – like promoting clown free birthday parties with awkward photos of children terrified by clowns and launching Not Happy Meals, but delivering Big Macs to people stuck in traffic jams doesn’t disappoint either.

Now to officially launch its delivery service in Chile, the fast food network has joined Uber Eats, to give away over 3,000 Whoppers to all those who live on a street with a name related to royalty. There are rather a lot of those, thanks to the Spanish conquest which filled the country with street names related to royalty and Europe’s monarchy.

The campaign, The King of the Streets, is rewarding all people who use the Uber Eats app, and order a Whopper from a royal street like Prince of Wales using the THEKINGOFTHESTREETS code, with their Whopper for free. 3,000 Whoppers will be handed out to the first people to activate the promo code.

“We want everyone to try our new Delivery service, with an initiative that only Burger King could make. Thanks to Uber Eats’ geolocalization features we are able to identify users who live in specific streets. But it’s also up to them to check if their street name is part of the promo, since a lot of names are not evident. We feel that’s highly interesting and even educational,” explained Soledad Fantuzzi, Burger King Chile marketing manager.

In a joint coding and mapping effort, Burger King and Uber Eats mapped over 216 streets across the metropolitan region, Viña del Mar, Valparaíso and Concepción, within the Uber Eats range, identifying streets like Fernando de Aragón, Prince of Wales, Queen Sofía, and also streets with the “Rey” or “Reyes” words on it, such as García Reyes or even Reynolds.
