So I've heard but I never had it. Kangaroo is another one that is very popular meat but you can't get that round here, its common in Australia/Asia. But ostriches are very sustainable compared to cows I believe. Big animal, lots of meat, replicates pretty good so it's not endangered. Thats why farms of them are becoming more common. Their leather is better compared to calf too, though it can look ugly unless done right. I do have a couple ostrich leather items.
kangaroo is also good. lion was the best burger I ever had though ---
