Tonle Sap Restaurant in Siem Reap is a spacious riverside buffet-style venue located at No. 117, National Road 6 in Svay Dangkum, just a short tuk‑tuk ride from the Old Market and Siem Reap Clinic.. The restaurant is particularly famous for its dinner buffet (typically around US $8–12 per person) paired with a traditional Apsara dance performance, adding a vibrant cultural experience to the meal.

The buffet offers a wide range of dishes—from Khmer, Thai, Chinese to other Asian cuisines, along with seafood stations and some Western-style fare. The dessert section, serving local sweets like glutinous rice and pumpkin custard, tends to be a favorite among diners. Reviews highlight the large dining hall and festive atmosphere, though some travelers caution that, during busy periods, the food quality and temperature can suffer, with several noting that hot dishes are often served lukewarm or cold.

Atmospherically, the restaurant combines modern Khmer décor with panoramic views of the Tonle Sap River—a scenic backdrop especially inviting at sunset. Service is generally friendly, though some guests reported average experience levels when the place is crowded. For groups or visitors seeking a lively evening of traditional performance and diverse Asian dishes at a modest price, Tonle Sap Restaurant offers a memorable option—just be sure to manage expectations for buffet-style dining quality.
