Fitzory and Collingwood in Melbourne used to be dingy cheap places to live and go out. There were a few boutique places that were more expensive. The last fifteen years its been taken over by overpriced venues. There's a KFC opening on Smith St and with a ~$8 chicken burger they'll be more accessible for many than $25 fancy eggs on toast. When I was in London, the first time I went to Oxford St (the monopoly st) it was full of franchise food and retail. It's not like the artists who made the area "cool" can afford to live there anymore anyway. Just the NIMBYs who've bought into the trendy vibe and don't want lower class franchises dragging their suburbs image down.
