Generally, the food situation in Tha Khaek is fairly poor with few options to mix things up. Travel Lodge is one of the busiest restaurants in town due to the captive audience they have, but the food is mediocre. There really isn't a whole lot else to eat around there. Head into town however and you have a few choices.
Located at Inthira Hotel down near the river, The Kitchen serves up a selection of Asian and Western fare in the most modern cafe in Tha Khaek. For breakfast there is fruit, eggs, baguettes and rice soup while at dinner burgers are the staple, with Lao salads also making an appearance. It's the most popular eatery in this area of town for foreigners.
Sang Fang Kong serves up delicious Thai food at great prices. We tried a few different dishes there and were consistently impressed with the quality of food on offer for such low prices. Prices are so low that far more locals eat there than foreigners. It's located on the road heading up to the roundabout from the river, just around the corner from Inthira.
Le Rendez-vous serves up mainly Lao food in a large indoor/outdoor shack. The outdoor terrace at the front is popular with Lao people after work who like to sip on a beer with ice cubes and watch the world go by. As the night progresses, more and more people arrive and snack on the cheap food. It's a decent spot for a beer and tasty Lao food. Located half way between the roundabout and the river and open for dinner only. T: (020) 5566 2220
Sabaidee Thakhek is a cheap shop catering towards foreigners who have had enough of the food at Travel Lodge. Located halfway between the river and the roundabout and about a 1.5 kilometres from Travel Lodge, Sabaidee serves up burgers, steaks and fried rice at very reasonable prices. It's open throughout the day, but we only ever saw one group of people eating there, which is a shame as it really does help to diversify the food scene in Tha Khaek.
