For the specific type of guy I'm thinking of its definitely too foreign.

If someone says Chinese food is their favourite/"the best", in my experience its more likely that they either have a really great restaurant near them and its just a food observation that they like the food there, rather than an opinion. Or they have a more deep seated reason for putting it on top, like having it as their home food, being a fanatic for it otherwise, they've decided that cuisines are the frontline of the political battle etc. Rather than it just being like a default option to pick whenever they need to declare someone the best at food.
