Re: What kind of food will have a hard time getting accepted in Pakistan?
I don't think there is any kind of "normal" food that would not be accepted in Pakistan.
You name it, Pakistan has it and LOVES it, be it Mexican, Italian, Portugese, American, Chinese, Middle Eastern, Indian (obviously), Russian, French... ANYTHING...
Taste being too bland is not really an issue, because one can always adjust according to their preference.
One possible rejection: Frog-legs = eeow
