If you're looking for a good local seafood restaurant, Seafood Station is definitely a good place to start. It's a small (mostly take-out) restaurant that makes everything fresh after you order. I've had their fried shrimp Po-Boy sandwiches and New England Clam Chowder two times and they're some of the best I've had. The slaw is not drenched in mayo and is not overly sweet. The chowder is not too creamy or dairy and has plenty of clams. Their fried oysters and fish (cod) and chips were great also, although once they have additional seating, the fries would certainly taste better eaten there when fries are crispy.
The owner says he is working on getting additional seating soon. Once that happens, the restaurant should quickly gain popularity.
