Of course, you're comparing apples and oranges because the price of a Big Mac is determined by the local market for Big Macs. In some places, McDonalds is considered upscale food because it's American, because it's less common, etc. In some places, the quality of McDonalds is much higher (kosher burgers in Israel, I think).
The data is also a good indication of brand consciousness in a country. People are paying a premium for the American brand. In Beijing, a big mac meal could cost double or triple what you could get at a local restaurant. It's seen as high class (partially because it is so expensive) and parents treat their kids to a happy meal on their birthday.
I would argue the east asian McD's are more seen as trendy than 'high class'. High class perhaps in pricing, but nobody sees it as 'high class food'.
