I really don't agree with the OP's views on either Mexican or Chinese food (two cuisines I loveeee). I've travelled a fair amount and all over Asia. I also made it a point to take a lot of food photos since so much of the stuff is stuff I've never had despite eating Asian food so frequently in North America. Here are some photos I took while in China that quite debunk the OP's judgment of Chinese food as being all just sloppily thrown together with a bunch of oil and no regard for taste (what crock). Also, all of these photos highlight traditional ways of Chinese cooking (steaming, stir frying, deep frying--that bloomin' onion-esque fish was SO good, boiling, grilling--grilled street lamb meat is PHENOMENAL!, and et cetera).
(Things to note in the image: that pile of chili peppers is Szechuan style cooking; notice the little tiny scorpions among the chilis--they were excellent; bottom right is some shrimp dish I had in Shanghai that was hands down the best shrimp Ive ever had in my LIFE--there is some oil for sure, but seriously whatever--I'd eat that every day; middle col rows 1 & 3 highlight some traditional Chinese preparation of steamed fish--really excellent; top right is a papaya with some sort of frog reproductive organs in a sweet tapiocay soup hehe; 1st col 2nd row is a traditional Beijing/northern noodle dish called "zha jiang mien" with some fermented bean paste and fresh & pickled veggies that was just amazing texturally and taste-wise and for < $1 USD. Bottom middle is a photo of a very typical Chinese fast food establishment of pick-your-own hotpot ingredients. Man I miss China!) Seriously, if I could only eat one type of food for the rest of my life, I'd have to go with Chinese just because within Chinese cooking there is so much variety (ranging from the dumplings of the north to seafood of the southeast to the spicy & sweet of the southwest where much of Thai food and Chinese food share origins) that I couldn't imagine getting bored with it; it's rather a pity that American Chinese food sucks. One thing that Chinese food does suck at is dessert. Sorry, but sweet bean paste is just not on the same level as chocolate souffle.
