There are lots of similar food options between the US and Japan like the Cheese burger, Filet-o fish and the Big Mac, as well as differences like how Japan serves wasabi chicken nuggets and the Tamago double Mac while parts of the US serve items such as Biscuits and Gravy and Johnsonville Brats.
Another great example of the different types of food around the world is McDonald's in Israel. They serve a variety foods ranging from the McKebab to chicken nuggets. Around 50 out of the 180 McDonald's restaurants are run by Kosher, meaning they cook and serve their food a certain way due to religion. For instance, Kosher McDonald's don't serve any pork.
