St-Louis BBQ ( and probably all over the USA south ).. oh man that was good shit right there.
Sushi is pretty smart but I don't know how much the stuff we eat has to do with actual sushi. Didn't know they had so much spicy mayo and grilled chicken to deep fry back in japan.
Love me some butter chicken too.
But yeah, most "authentic" foreign food is not good because they come from poorer countries who have a harder time accessing actual good things like butter, refined sugars and chicken and they have to rely on beef penis and dried squid to sustain themselves ( or in some more extreme cases, vegetables). The "authentic" foods we tend to like from other places are generally not very ancient and mostly consist of fat / sugar / carbs / meat / spices... For instance, sushi, which was mentioned many times here... I bet most people like the more recent sushi creations to the actual authentic traditional raw / marinated fish forms.
For instance, the california roll, the most popular sushi in america, is a novelty for Japanese people ( http://voices.yahoo.com/the-california-roll-most-popular-sus hi-roll-in-437539.html ). In Japan, the raw fish nigiri sushi are vastly more common than all the different kinds of rolls we find here in America.
The same goes for "Chinese food" which is not really Chinese food so much as American food made by Chinese people. If you've never been to a good Chinatown, you don't know the horrors that Chinese people ACTUALLY eat. Holy shit. Dried pizza-flavoured anchovies anyone? YUM!
99.9% of the food you've never tried won't beat a good burger or a scoop of ice cream, basically. So don't feel too bad guys!
And remember the rule of thumb: If a new food doesn't contain sugar, meat or fat, it's probably shitty.
