Chivit Thamma Da is probably the most "special" buildings in Chiang Rai.
The buildings are built a little bit in old colonial style and are in a beautiful garden on Kok River. They have many different type of dishes that are almost as special as the houses. The food is great and the cakes (!) are even better! And they have many different type of beer, many English Ales and also many different wines.
The owners are a young Swedish guy and his beautiful Thai wife.
