Coolest place in Sydney

A couple of English guys took me to the coolest place in Sydney. I didn't know what to expect, but began to wonder when they had us putting on big coats and gloves. The place was called Minus 5. The name says it all; they keep the place at minus 5 degrees celsius. (Zero is freezing). Everything is made of ice! They have ice sculptures of all the Sydney attractions and some Aussie animals, even the seats are ice. You are only allowed to say in for 30 min and believe me, you don't want to stay for much longer. It was nice to come back out to the warm summer weather.
