Camouflaged among car dealerships and fast-food chains on strip-mall-ish 82nd Avenue is the Thai restaurant Arawan. Its deceptively plain building and blander-than-bland interior disappear once you take your first bite of pla tod rad king ($9.95)-battered Basa fish topped with ginger, onions, mushrooms and celery with a tasty soy sauce. And as you complement this delicious meal with a light, crisp Singha Thai beer ($3.50), the issue of the chefs not majoring in interior design is appropriately forgotten. (BV)
