A fact is that a country's traiationdl cuisine tastes different everywhere. If you tell an American, who had eaten real Mexican food, that Rubios fish tacos are the best, he will disagree.A Turkish kebab, although highly appreciated by everyone in Germany, will still taste different/ better in Turkey.At the same time it is not unlikely to see a Korean running a Japanese Sushi restaurant in Germany e.g., as, sadly enough, it will not make a huge different to the one enjoying it.
