Went to have a drink with our kids out of the heat. Allowed to sign in and sit down. Once up to get a drink was told that males have to have a polo or tshirt on. No singlets... its 47 out side but all the females are allowed to wear a singlet. Seems a bit unfair to me. We left. Did look like a nice club though shame we really didn't get to see it
