I guess exotic is relative, someone in here saying kangaroo is eaten all around Australia and Alligator is reasonably common here. Someone has goat as exotic but it seems common most everywhere.
I'm gonna go with the turtle soup my grandma got us at a restaurant when I was little (family very Louisiana on my dad's side), I remember it being good. Don't think I'd eat anything even remotely endangered now, they were not back then.
Husband still raves about Indonesian fried frog legs, he lived there for years growing up.
Yeah we Aussies eat kangaroo and crocodile, kangaroo is very normal here, they sell it in supermarket chains, but mostly it is wallaby not roo (labelled as roo). It just tastes like venison. I reckon you and I are the only ones who have eaten frogs legs in this list though.
