One more reason KA>CX: melanine! :-)
CX could potentially be bad for your health :-)
Breakfast on PVG-HKG in Y includes dairy products made by Yili, the very same company that recalled all their baby milk for mercury poisoning!
Either CX has no control over its catering, don't read newspapers or simply couldn't care less.
If you pay the premium to fly CX rather than MU at least you should deserve to be fed food that is safe and that pax dare to eat right?
