Tonle Mekong Restaurant in Siem Reap is a large-scale, buffet-style venue situated at No. 110 on Street No. 6 (National Road 6), in the Svay Dangkum area of the city. It serves a broad international spread with a strong emphasis on Khmer cuisine—ranging from curry chicken and vegetable stir-fries to a vast dessert section including local sweets like coconut pancakes (“kanom krok”). Evening performances of traditional Apsara dance and folk routines elevate the atmosphere, offering entertaining cultural value alongside the meal.

Popular with tour groups, the restaurant’s bustling hall can feel overcrowded, especially during peak dinner hours. Many patrons note that hot dishes may be slow to refill or served lukewarm, and line control at buffet stations is minimal—making it feel somewhat chaotic. While food quality is often described as average or “serviceable,” the buffet’s variety, affordability (typically $$–$$$ range), and lively ambience earn it decent marks—TripAdvisor lists its average rating at around 3.5/5 from nearly 60 reviews.
