Who says Thai food has to be sweat-inducing? Sala Thai makes the food as spicy as you wish, because this chef is interested in flavor, not fire. The subtly seasoned dishes are pla goong (shrimp in lime dressing) or chicken sautéed with ginger and pineapple. But if you're looking for heat, don't miss the palate-inflaming, three-alarm stir-fry plates. Mirrored walls, live music and warm lights soften this small dining room. The U Street location was the first, but spinoffs can be found downtown, in the rising Petworth neighborhood, in the still-gentrifying Upper Northeast area, and in the Maryland suburb of Bethesda.
