I tried shark meat once. Don't remember how it tasted like. Pretty sure it tasted like normal fish though.
Also tried frog legs, they were yum.
Escargots too, but i guess they're not very exotic.
No, once in a local super they were selling kangaroos' meet, I was actually curious to know what was the taste of it so I slightly wanted to buy it, but then I looked at the price and my curiosity ended.
