I will be traveling to Cape Cod this weekend . I already know where I will be eating on the Cape but I would like to stop for lunch on the way there from NYC (route: I-95 to I-195 to Rte 25 etc.), probably near Providence. I am willing to stray 15-20 minutes form my route. Suggestions for excellent informal local seafood, or other not to be missed venues, would be greatly appreciated.
