Hmmmm, with having an cullinary adventurous dad, over time I have tried:
ox tongue - not bad
tripe - yuck
sheeps brains/liver/kidney - gag and retch
eel - quiet tasty
crocodile - great in a stir fry
kangaroo - lovely medium rare steak
venison - as above
quail - bit fiddly
snake - bit like chicken

so.....i will reserve judgement on the creepy crawly snacks, only cause medications make my tummy really sensitive.

Oh and I have also had my brothers omlet for which you need a cast iron stomach!
