It's on the menu in China everywhere. I once knew a guy who went on a group tour of China back in the '80's. At one restaurant, the lavish multi-course meal they were to be served listed all the various items, and #4 on the list was rat. So they all whispered to each other, "Don't eat #4! Don't eat #4!"
To the group's chagrin, the courses were served in a different order than as presented on the menu. The fourth dish served was steamed veggies. They'd already eaten the rat.
The various world cultures and their embrace of, or revulsion to, various foodstuffs is an interesting study. For instance, Lewis and Clark resorted on their exploration to wild dog meat. After being initially repulsed, the members of their party admitted that it was "rather tasty."
My wife is Asian, hates cheese, thinks its disgusting, like eating a chunk of lard.
On the cultural distinctions, there's a very interesting book called Good to Eat: Riddles of Food and Culture (basically blows away lots of cultural taboos and favorites, e.g., Atkins would love it), and another one I can't recall that was basically a cookbook for ethnic stuff we'd consider disgusting, Hawaiian Roast Puppy Dog was one memorable recipe.
