Eating options in Don Khong are largely limited to the handful of restaurants that line the river near the boat ramp. Our pick of these restaurants is the one at Don Khong Guesthouse where we had some fantastic Lao food and a tasty rice soup.
Ratana Guesthouse's restaurant is another top option with a fairly standard menu of Lao food. You'll often see people dining here at night.
Pon's Guesthouse also has a similar menu to the others on this road, but we have it on good advice that the Lao Lao here packs a punch. This is a good place for a simple Lao meal and perhaps a potent nightcap.
