I've become hooked on Dok Bua after my first taste a month ago based on Chowhound recommendations. It not only met but exceeded my expectations. The service is friendly, the portions are large and the food is fabulous. After 4 visits, my favorite dishes are:
Yum Nua (Y2): beef salad loaded with herbal flavors and light heat.
Stir fried catfish in hot sauce (CK12): features large cross sections, with bone easily removeable, of perfectly cooked fish in a very spicy red pepper sauce, along with string beans.
