I had gone there in evening time at sunset, we seen there is on the main road side there is a of lot of shops & Restuarant there and also on the warf also there is some restaurants also. I did not know about perfect reply of your question.
If you search on Google, coffee places on Stern's Wharf, you will get details.
I believe that the warf opens around 8am, so i would imagine that they are serving coffee then. If not there is a 7eleven regards ght around the corner - open 24hrs
