Own Home is one of many great restuarants that line the streets of Pai. With an exhaustive menu that takes in many traditional Thai dishes, as well as a healthy supply of Western food, Own Home was a regular stopping point for lunch.
While all of the dishes we had were great, favorites included the chicken pizza and a number of the salads. Make sure you get a fruit baan (shake) here--cheap and very yummy.
The service is also quite good, and the location is very central to everything else that is going on. As a guideline, meals for four people (including drinks) cost around the 150B to 200B mark (US$5 or less) for all of us.
