Nothing TOO weird. Naturally most of the normal meats (chicken, turkey, beef, pork, fish, shrimp, crab) I've tried.
As far as anything else, I've tried:
Deer - Ate it all my life. Just a normal meat to me that tastes vaguely like beef (better than beef if slow cooked, not as good when grilled)
Elk - Only tried it once, but not much different than deer.
Duck - Honestly, I don't care for it that much. Tastes like liver to me.
Bison - It's OK. Like beef with a funny taste. I'll eat it, but not over beef.
Crayfish - Love the little buggers fried
.
Lobster - Tastes like a rubbery shrimp to me. Enjoyable, but not nearly as good as shrimp and certainly not worth the price.
Gator - Tastes like *fishy* chicken. Don't like it.
Octopus - Good, but very, very chewy.
Squid - VERY good fried with some lime juice. Just a tad chewy, but not as bad as the octopus.
As far of PARTS of an animal, I've tried tacos made with beef tongue and beef cheek meat. Both were decent.
