The Chinese approach to Western foods is the same as for Western people. Fine to have around sometimes, but it isn't something you'd take seriously. You stick strictly to native Chinese items for your main course. Western elements, even perfectly serious ones like, say, bread, are OK for a diversion now and then. Just add plenty of sugar to cover up that nasty Western taste. Remind anyone of their workplace? Oh, putting a hot dog in a doughnut is completely ridiculous? It's OK, it's not like we defiled hongshao qiezi. That would be offensive.
