This great Thai-Isan (North-Eastern) restaurant is located in a Thai-style house in a quiet street off Paholyothin Road. There are 2 wooden terraces surrounded by green outside, and inside you can enjoy the air-conditioned space on two levels decorated with Thai art.
The standard Isan fare like som tam (papaya salad), kay yaang (grilled chicken) and sticky rice is delicious, but the special mushroom dishes and ice cream desserts are worthwhile too. Of course the beer bottles are big. The service is friendly.
