Red Lantern

Given that Australia is the driest continent in the world (after Antarctica, where most humans can't live comfortably for long anyway), conserving our water supplies is crucial to our sustainable future. And that's why Red Lantern, the most awarded Vietnamese restaurant on the planet, has installed its own rain tanks, as well as a wok cooking system that works without a drop of water. The majority of produce comes from organic farms and used-up cooking oil heads to Cookers, where it's turned into bio fuel. Red Lantern head chef Mark Jensen is so passionate about sustainability, he's written a book about it.
