I second that. There is a mile difference between the sorry excuse of a burger that’s called Big Tasty and McCrispy in the Netherlands versus the already way better proportioned and fresher one you get in Germany, up to the better ones in Italy.

Besides the bun, it is noticeable in every part. The amounts and quality of the sauce, vegetables, and meat. And finally how the burger is presented.

So if this difference can occur within 1000km of each other in the same continent, I fully accept that it is even more varied in the whole world.

I’d say the only place I’ve experienced McDonald’s to be ‘extremely’ different is in India due to the obvious prevalence of vegetarianism and outlawing of beef.

In other countries the do have a lot of additional meals which are specific to their local taste (rice/fried chicken/different sauces) but the core burgers like a Big Mac, mcChicken and sides such as fries are there.

"extremely different" is an exaggeration. It's mostly the same with some local differences.
