Underground dining

Hi all,

I'm new to the forum. This subject has probably been done before but I'm interested finding a particular "restaurant" in Melbourne, Australia called Zingara Cucina. I have been trying to find someone who has dined there in order to validate its existence. In my expanding search network I have been commonly getting the response that it does not exist and is just an elaborate hoax played out by a certain Marketing exec from an Ad Agency. Can anyone shed some light on this?

Regards
