Replacing 'unique' with 'individual' might be better English but I'm sure that your English is far better than our Dutch anyway ;-)
(Goedenavond!)
Here in the UK there's often a bit of confusion about what is meant by 'Indian' food. That comes about because when the whole of the Indian sub-continent was part of the British Empire 'Indian' restaurants started to appear in this country. However the families coming here to run those restaurants mainly came from those parts of the sub-continent which later found independence as East Bengal, then as East Pakistan and finally as Bangladesh. So the vast majority of 'Indian' restaurants in the UK are run by families with their roots in what is now Bangladesh, serving cuisine largely associated with that part of the world.
So I'd separate what most people here call 'Indian' food (which is really Bangladeshi food) from, say, the food of southern India. (I'd associate dosas with Kerala but not with the more northern parts of India, for example).
So that gives you 'Indian' (= Bangladeshi) food as one reasonably distinctive style of cuisine, with 'South Indian' as an entirely separate one. Other types of Asian food which are commonly found here in the UK, with each having something distinctive about them, would be Chinese, Japanese, Thai, Vietnamese, Turkish, Lebanese and Malaysian. That gives a total of nine distinctive food styles (most of which I suspect you could find just as easily in Amsterdam as we can in London). To look for one more, to make your list up to ten countries (and with the emphasis on finding something totally unrepresented elsewhere in the list), I'd suggest looking to those Asian countries which were formerly members of the Soviet Union, such as Kazakhstan.
