Siem Reap's proximity to the Tonle Sap — Southeast Asia's largest freshwater lake — means fresh fish is central to local cuisine. The lake provides abundant supplies of freshwater fish including snakehead, catfish, tilapia, and river prawns, all of which feature prominently on local and tourist restaurant menus. Beyond freshwater fish, seafood restaurants also bring in saltwater species from the coast — shrimp, squid, crabs, and lobster arrive from Sihanoukville and Koh Kong, typically via Phnom Penh. Several Thai-style seafood grills have opened in Siem Reap, where whole fish and shellfish are cooked over charcoal and served with chili dipping sauces and fresh herbs. Prices for freshwater fish dishes start around $8-15, while premium saltwater seafood dishes can reach $20-35. Live tanks are found at some larger establishments, letting you pick your fish or crabs before they're cooked. The best seafood restaurants are popular with expats and food-curious tourists who want to experience the lake fish that is so important to Cambodian culture and diet. Tonle Sap fish amok — the traditional steamed curry — is a must-try. Grilled freshwater prawns, marinated simply in salt, garlic, and lemongrass, are a local favorite that disappear quickly at dinner service.
