Never had bear. Have had emu, wallaby, venison, crocodile, boar.. and all kinds of seafood like trepang and cuttlefish and jellyfish. Kangaroo is really excellent as well as being inexpensive and readily available.
And yeah, I'll try anything once. I try and order things I have never tasted. If I don't actually know what it is because it's not listed in english, even better
