For a comparatively small town, Siem Reap offers an amazing range of cuisines and dining venues. The emphasis is, of course, on Khmer food, which can be found at restaurants across town, but European and other Asian cuisines are also well represented, including Italian, Thai, German, Vietnamese, Indian, Chinese, Korean, Japanese and, of course, French. Given Cambodia's long relationship with France and France's gastronomic traditions, it is no surprise some of the town’s finest venues offer French cuisine. Also of interest to the gastronome, some finer venues are offering Khmer-Asian-western fusion and contemporary cuisines quite unique to Cambodia. Restaurants are scattered across the town but none is more than a 5-minute tuk-tuk ride away. Many restaurants, including several specializing in Khmer food, are concentrated into the Old Market area, especially around ‘Pub Street.’ Make sure to set aside one dinner to attend a traditional 'Apsara' dance performance.

I agree, siem reap has a wide variety of cuisine options. I was there for a little less than a week, and ate such delicious meals every day. Pub street does offer a lot and you can find any nationality of food served, but I tried to find traditional khmer places. I don't remember the name of it, but I found a vegetarian restaurant in the Old Market area, and it served such unique and delicious dishes.
