you guys must eat at McDonalds a real lot to be able to discern any difference, it's exactly the same food in slightly different shapes.
(Why am I eating McDonalds in Europe? Sometimes when you get off a train and don't have your bearings yet in a place, something fast that's a known quantity is the way to go even if it pales to other options you'll find soon).
(I don't notice a ton of difference between USA McDonald's and other ones, though the taste can be slightly different, and I don't usually frequent McDonalds in dense urban areas in the USA.)
