I have no problem with people who say "I don't like X dish, or Y ingredient" but I recently went out to lunch with friends and suggested Vietnamese, only to be shot down by one friend who said he doesn't like it. It always strikes me as odd that someone can't find SOMETHING to eat at a general restaurant (steakhouses, sushi places, etc, that specialize are obviously a different thing).
Part of the reason that it makes me confused is that I was (and still am, a bit) a picky eater, and I've never been to a place where I said "There is nothing here I can eat." I may be required to get a bit creative at places with a limited menu, but I never starve. And in this case, I wasn't suggesting a place limited to pho, but with a full range of Vietnamese dishes.
So what do you think? Is it possible to dislike EVERYTHING a country cooks?
