Coffee shops in Da Nang

I did a list of the coffee shops I’ve visiting these weeks. A lot, usually one or two per day.Da Nang is a great place for writing in cafes. However there is a culture of smoke while taking coffee. Terraces are not usable for that, which is sad. Also many open cafes (no walls) suffer from the same issue. Some of them were great, excellent decoration, atmosphere, tables, etc., but smoke comes in continuously so I had to lower the rating of some of them to 0.5.I try to not be very picky while writing in cafes, otherwise I will never be confortable. But I really can’t stand aircon or smoke.
