Queen Victoria Market !
I was a bad photographer when I visited there for the first time, so I've just tried it again.
"The Queen Victoria Market (also known locally as Vic Market or Queen Vic) is a major landmark in Melbourne, Australia, and at around seven hectares (17 acres) is the largest open air market in the Southern Hemisphere." (Quoted from Wikipedia)
Anyway, it is so big that you can get lost, and has pretty much anything you need, for example, food, clothes, books, souvenir etc. Then, it is very lively.
You must try! See you.
