Use the Free Telstra Wifi network which is broadcast from across the street. The signal is strongest closer to the street, but you can still get it in the back, the free WiFi has solid download speeds.
Modern, clean interior with bench seating along one side. Kind of a hip spot that takes coffee seriously. The front is entirely open to the street bringing lots of fresh air and indirect sunlight. The seating is mostly a single bench with 7 tiny, one-person tables.
