Actually not too bad, but both are very lean and you do have to be careful when cooking them as they can dry out quite easily as there is fuck all fat to break down and keep it moist. Emu is a dark meat and doesn't taste like chicken, even though it is a fucking big chook! Roo is a bit earthy and gamey. Both require decent spices to give them some flavour, but I would rather have a good old grass fed steak with nice marbled fat, or a spring lamb chop on the barbie.
