In Mexico a Indian family fed us burritos made from dog meat (a delicacy to them). My friend puked, but I ate half already so I finished it to be polite. It was greasy, but not much different taste than beef. I think it is in our mind that we can't eat these "pets".
In China, my girlfriend fed me frog and turtle. The frog wasn't bad except too many small bones. I didn't like turtle.
