Near our hotel was the old-school 海安咖啡室 Hoi On Cafe which we noticed when we were on Ding Ding.
Established since 60 years ago, the name of the cafe was meant as well-wishes to the sailors, as the cafe was located near the pier. Nowadays, this place seem to be quite popular with tourists.
The staff understood Mandarin well enough, and were extremely patient and kind, e.g. there was a group who wanted to change tables after their orders had arrived, and the staff helped them to shift the food without complaints; they gave us water when they saw that we were about to take our medications with coffee / tea, which was much appreciated!
