We introduce a dielectric photonic metamaterial presenting a giant nonlinear optical response driven by resonant optomechanical forces. Being inherently free of Joule losses, it exhibits optical bistability at intensity levels of less than 0.2 mW mu m(-2) and, furthermore, manifests nonlinear asymmetric transmission with a forward : backward optical extinction ratio of more than 30 dB.
