Sure, in america you might have a hard time finding a restaurant that serves both cheese burgers and american style spaghetti w/ meatballs. But when abroad you might find an 'american restaurant' that has both on their menu.

I think it's just down to people starting a 'foreign restaurant', there may just not be enough market for a specialty foreign food so you pack in a few popular dishes together and run a 'foreign country restaurant' instead of just a specialty place.

Certainly even in my corner of america (the pnw) where sushi is quite popular, we have a mix of places that just do sushi, or most do sushi and a few other dishes, or just a 'japanese restaurant'.

Sure, and in japan you might find the japanese equivalent. The basic argument was though that you find these ultra specialized places mostly within the country of the foods origin and that they are more common than more broad places. Which I think is a worldwide trueism.
