I had the pleasure of trying a lovely double shot single origin flat white from a coffee venue recently and felt compelled to share this info.
It's in the shopping arcade in the Woolworths complex at Prospect Vale.

It's in the centre of the arcade right outside Woolies, not one of the shops on the side.
I'll be going back so I'll get their name, but this should be enough to direct people there.
They have 2 grinders, a blend and a single origin.

Enjoy!
