Baan Panburi boasts of having the best restaurant in Thong Nai Pan Noi in Ko Pha Ngan. Though I never ventured out to try the other restaurants in this small beach, the dishes they serve at the Terrace Restaurant is simply sumptuous and reasonably priced.
The menu displays a variety of cuisine from Western to Asian, with fares both meat lovers and vegetarians would enjoy. In the evening, you can also partake in their barbeque of fresh seafood.
