Here is a simple, clever marketing ploy on how to get customers. Replace standard dark chairs at a couple of tables with a brightly coloured ones; in this case vivid orange. I hope this idea works for this well positioned restaurant at Martin Place.
On this occasion it was totally empty, but admittedly it was a mid afternoon, so most people are at work. It is also a bit too early for Summer holidays tourists.
On photography side it made a nice choice for selective colour photograph.
