If you need to stay the night on your way through Buriram, I vil recommend Rainbow Hill Hotel on route 24. It is a new hotel with 4 double bungalows, owned by a French guy with a taste for quality. I was pleasantly surprised after having stayed at some shitty places, and especially the bahtroom was impressive for a countryside hotel. They don't have a restaurant, but the staff offered to go at get some food for me. They charged 40 baht for fried rice with chicken, no extra for getting it. Very friendly staff, and they called the owner to talk to me to make sure I had everything I needed. The hotel is reasonable close to Phanom Rung National Park, where you will find ruins like in Angkor Wat, although much smaller.
