I once did some not very serious google-based statistics to look at the number of immigrants vs the number of restaurants of that type. I used Italy, where I lived at the time, because it was easy to get the immigration stats and because most immigration is pretty recent. There are, for instance, a lot of Filipinos living and working in Italy, but not many restaurants. There are a ton of "Japanese" restaurants, but not very many immigrants.
