Would you knowingly eat horse meat?
I voted "other" - when I was in Japan, I was invited to someone's house where a spread of food was laid out. There was jerky there so I grabbed one. Only after I got through several bites was I told it was horse. I don't remember finishing it but I don't remember it being bad. I might try it again.
Several people mentioned venison - I've known several people that suggested i tried what they made and I didn't like it either. I've had it since and I like it, but not everyone knows how to cook it properly. Stephan Pyle knows how to make a mean chicken-fried venison steak!
I'm a fan of bison/buffalo, I highly suggest trying it if you haven't.
