I was in Sydneys chinatown a few years back and above one of the restaurants I could see into a burnt out old apartment building that 100% reminded me of the matrix. I doubt it would have been too hard to find.
Oh when I was there 24 years ago Chinatown wasn't all that bad. We often went to eat there, or go to paddy's market (which was not quite in chinatown but on the edge of it).
It was also the only "ethnic town" that actually felt like one. "Koreatown" and "Thai town" were just normal CBD streets with maybe one or two massage parlors. I think those names were invented more for publicity than anything.
I wish I could go back to Oceania for a long trip some day. But it's so far and expensive from Europe :'(
PS Chinatown isn't even like a neighbourhood, it's like 2 streets ;) But the Chinese influence is everywhere in Sydney. Even in the neighbourhood I lived there was this really cool Chinese temple in the middle of a normal terrace housing block.
Yeah, at street level I couldnt fault the place. But having done a lot of wireless engineering I have a tendency to look up, and the places were like 5th storey and above. Shattered windows, burnt out interiors that sort of thing.
