Um, well we only list the stuff that's specific or that originates from our country, but we obviously do have stuff from all over the world as well
Immigrants that actually cook the exact same way are extremely rare, and they're only a few samples of a whole culture. Foreign restaurants we have in Paris (and there are more foreign restaurants than french restaurants...) are nowhere near comparable to the stuff you can eat in the country itself. Stuff like Spanish crude ham can only be found there, the imports are just bad by comparison. Same with local cheese, that's the kind of food you'll never find in a store even in the original country, let alone as an export. Bread... I've ever found a single bread outside of France that was even remotely comestible. I've eaten the best calzone in my life in Napoli, and no other ever came close.
I love the Indian stuff with loads of spices, and I'm fairly sure if I could afford travellingthere it would be even more delicious~
