Hmmm. I've had rabbit prepared 5 different ways at a very expensive restaurant once (had just gotten a bonus for the first time in my life and it landed on my wife and I's anniversary). It was fantastic, like dark meat from a turkey or chicken, but a tad gamey which I didn't mind.
Venison is delicious, as is elk. Buffalo burgers are solid, not much different than regular. I've had ostrich jerky but it's pretty much the same as most other jerkys by that point.
Had shark once, was very good and similar to swordfish.
Funnily enough all of these things I tried in the US, and none while actually traveling abroad despite adventures to most of the continents at this point.
