I had to have some American food on my trip to India. The spices, the lack of animal protein and the general unfamiliarity of the food just destroyed me. I eventually threated a cow in order to be taken to a KFC (and I hate KFCs in the U.S.) And we worked out that "English food" means "boil it and put butter on it" to Indians. :)

I could actually see someone being curious enough to request their own food in another country - just to see what the interpretation would be... But... er... I probably ask my guests, and not asssume they want a bad imitation of their own cuisine.
