In case you're curious - ostrich fillet is pretty tender, it looks a lot like beef, except that it's slightly darker in colour and you will likely never see fat on the meat. Ostrich is in fact one of the healthiest meats with a fat content lower than that of skinless chicken or turkey, and high in protein and iron.
All this said, while ostrich meat is fairly similar to beef, I have to say that I still prefer a good, thick, T-Bone steak - every time. :)
