Mako Cafe and Bar
Shop 26 Gungahlin Market Place,
.....is said to have great coffee,..though I havent tried there myself yet, so I really cannot recommend from experience.
There are tonnes of coffee places in the main street of Gungahlin,.. but most are your usual GJ, SB, CG etc...theyre all there,I had a laugh. Good luck and let me know if you find a good one ;D .
In Dickson,.. go down the very end of Wooley Street,.. on the corner there is a nice coffee joint,.. forgot the name sorry.. but it was serving great coffee when I went there about 12months ago.
