In Nai Yang, located on the left hand side when driving from the airport towards Phuket town. Not easy to find, please look at the map before you go there. One-O-One Restaurant is one of the best, if not the best Isarn food (north/east Thailand) restaurant of Phuket. The menu shows pictures, but we recommend a Thai should come with you. It makes ordering easier. Always tell how spicy you want the dishes.
