This started off as a way to play around with the My Maps feature on Google Maps, then grew to a point where visitors to Sydney found it kind of useful. It shows places to eat, drink, get coffee and (for the weary traveller) corner stores that stay open late.
For the uninitiated: note that I am not a Sydney native and no doubt there are several million other places you could go. This map is just places we've found in the past year and liked enough to consider going back.
