I have eaten many exotic fish in my time, especially when I'm in Australia visiiting my family as my uncle owns a dive school so there is plenty of fresh fish available.
I have eaten a few exotic mammals aswell.. I think Kangaroo was the nicest (It was a road kill, we found on the way back from fishing one morning - still warm)
I love Cod, but am also worried about the over fishing, so no more Harry Ramsdens for me
