In general I would recommend dining with any of the food vendors in the archeological park while you are exploring the temples. There are many food vendors to choose from near most of the temples. If you are having trouble locating a food stall check near the craft stalls. Ice cream and fruit vendors stroll the grounds selling their wares and locals also set-up shop with full hot meals in a variety of places. The food is safe to consume. They cook it right there in front of you so it comes out hot, fresh and delicious. The offerings are primarily Khmer cuisine and most of the stalls are family run so the children are helping out right alongside their parents. And even though this is a touristy area the food is still very inexpensive. The food stalls are a great alternative to returning to Siem Reap for lunch, especially when visiting the more distant temples.
Favorite Dish: If you’re not that adventurous or can’t quite decide I always recommend the chicken with ginger and garlic. It’s a delicious and safe choice. I found the Khmer food generally simple but extremely flavorful and it quickly became a favorite of mine.
Prices: less than US$10
