I work in Wilmington MA, and in search of tasty lunches have found what at least one other chowhound in the area confirms: Wilmington and Reading are a culinary wasteland. There are within easy driving distance of my workplace at least four Chinese restaurants, all of them discouraging. As for the rest, one has the choice of overpriced trendoid food, run-of-the-mill or worse subs, and McDonaldsBurgerKing. I note here a couple of exceptions, in the hope that someone can point out others.
Generally speaking, if the Royal Dynasty on Route 129 in Wilmington is any sort of bright spot in your gustatory life, then your case is sad indeed. However, I've found two dishes there which are easily worth eating. The first is the he wonton soup, regularly available. Though the broth is faint, it's crowded with huge chunks of vegetables, a thick slice or two of roast pork, and very-well-stuffed wontons. The second is the pad thai which is occasionally among the specials, a dish free of the gluey sauces which encumber most of the establishment's productions, and made of tender sweetish noodles, ground nuts, egg, onions, and big shrimp. Neither offering will impress the gourmet at all, but both are simple and tasty.
