It would be in a Family restaurant / bar setup - somewhere that hoons would not frequent. In an open area where the machines are in full view of staff.
The kids go to the indoor playground, mum and dad have a quiet meal and a beer - then dad plays pins for an hour or two
What about Zagames in the right suburb?
That's the name I was thinking of. There's one in Reservoir (Edwardes St). There used to be pins in there, but they are "hidden" around a concealed corner.
