They have a saying in China that the people in Guangdong province (Canton) eat everything with legs, except tables, and they eat everything with wings, except airplanes. Hence, pretty much everything is fair game.
When I lived there, the most unique things I ate were camel, horse, yak, and inscets. The horse was not very good. I would try dog if given the opportunity.
My philosophy is that if other humans eat it, I can eat it too: except, of course, the urine eggs.
Yes, that is very true as well.
Th most exotic thing I have ate was shark meat. Shark fin soup doesn't count!
