The Royal Exchange Hotel, opposite Southern Cross Station in Melbourne.
This is a quiet bistro and bar below street level and just across the road from the railway station. I arrived for a very late breakfast and ordered the Big Breakfast for $15 with coffee.
The Big Breakfast was indeed big, and came with coffee. Quite a meal.
I set up here and worked for some time. It is quiet, dimly lit and was a battery saver, allowing me to dim the brightness of my HP Chromebook 11 way down. After working for some 30 minutes, the Chromebook was showing 8.5 hrs of battery life remaining.
