Chiang Khan also hosts at least three restaurants focusing specifically on Vietnamese food. We had an excellent spread of khanom bueang (or banh xeo in Vietnamese) and khanom pak mor (rice paper dumpling with ground pork and a finely chopped leafy green) at a shop on Sri Chiang Khan Road, directly across from Soi 17. They're open only during daylight hours; look for a big red sign with Thai script and some pictures of the available dishes.
