Interesting project. You don't need to focus on inner Melbourne if you are looking for the seedy side of the industry. My late father basically was the first (or one of the first) operators that started in the "Expresso Bars" in Carlton in the mid 50's. Plenty of stories, but not many (if any) photos of those days. If you walked into any of these locations with a camera, you left without the camera, and a very sore head.. The 80's was similar, with the turf wars etc - but I will mention something about the Underbelly Series, straight from someone who knew the amusement scene intimately, and I quote ;

"TV series is a load of Bullshiezen"..
