After a slow and shaky start, with probably several licensees, Subway is almost every popular area in Australia, with more outlets than McDonald's, and with most fast food franchises now selling similar sandwich/baguette product lines.
Before this success I fondly remember the Subway outlet in Sydney's Kings Cross, not for the fact that it was so badly managed (but great for regular customers), but for the great people watching on the main street - right betwwen the stripshows, street walkers, bikies, locals and addicts.
