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.

Goat. Ate it in Greece. Roasted with fine herbs. It was delicious.

Does jellyfish count? It's a bit boring to be honest!

Second would be sea snails and they were pretty nice.

live sea urchin

I once made tacos out of beaver meat. Pretty good stuff. It was like a very tender steak

Alpaca.

I had a steak. It was fantastic.

Moose and reindeer.

Bison steak. I’m not a steak person so it was likely wasted on me.
