McDonalds in the US is generally cheaper than the same in the rest of the world. The company decided they don't like being the value option and so raised prices trying to seem premium.
I don't eat there at home, I'm not interested in trying them in other countries.
I still giggle at how McD tried to market itself as the "healthy" option, especially targeting "girls and women", at least here in Germany, with Heidi Klum and some of her Germany's Next Topmodels as the advertisement figures. They even changed their logo from red + gold to green + gold. That was a few years back.
