The reason why McD tastes the same everywhere in the world is because of strict protocols like this. Ever wondered why Domino’s tastes very different depending on the country? I prefer predictability in quality and that is one thing that McD gets right
I've heard people say good things about dominos in Switzerland in France but I have zero interest in trying it to compare with my experience in the USA.
That's not even remotely true. McDonald's has completely different menu items in some countries, and the common ones frequently have ingredients of very different qualities.
Not to put too fine a point on it, but the quality in the US is, shall we say, not at the top of the list.
