This is a great Thai restaurant that seems to be unknown to the foreigners in Chiangmai. No tour buses here, just many Thai people who have come for the excellent food and the ambiance. You eat while sitting around or above the small lake. There are fountains and running water to add atmosphere. The central jetty is anchored and has no roof, while two others are floating jetties with thatched roofs to keep you cool under the sun. One section on the shore has a tin roof with water running over the roof for both atmosphere and your comfort. There are many tables (over 150 at my count) and a large staff, but even so the restaurant can get quite busy at times.
A note to those concerned about hygiene: the restaurant proudly displays signs announcing that the Sanitation Department has ranked them as "Very Good" and that every container is sterilized. Be at ease and enjoy the food without worries. Not one problem reported from the food, so I accept their signs at face value. The bathrooms were quite clean and had no odors. Foreigners should be aware: these are authentic Thai style toilets and not the Western models we know and love (at least when the need is upon us). If you don't like Thai-style toilets, plan your affairs accordingly.
