McDonald’s Canada just had a viral marketing video pleasing viewers and fans by being more open about their advertising practices. Namely, why the food in McD’s advertisements looks different than the real thing

Now, they are continuing with their very open and honest Your Questions campaign, allowing customers to ask their most burning wonders. In their latest video, McD’s seriously drops the gauntlet and shakes up the fast food world.

They show how to make the world famous Big Mac Secret Sauce, and how to contruct a perfect Big Mac, all by a real McDonald’s chef with store bought ingredients. Of course, the authentic Mac Sauce in restaurants is dairy, so there’s definitely something still kept secret. Which expected from the world’s largest hamburger restaurant chain.

Marketing. You’re doing it right.
