Our readers know about Rawley's old hot dog joint in Fairfield from Gwynnie, but this is as good - better for seafood fans: Westfair Fish and Chips in Westport. It's right off I-95 for you hungry east-coast travellers.
Modest little clam shack has a fine raw bar too. Worth a trip, or makes a longer trip enjoyable. I will drive a good ways for fresh oysters, fried clam bellies, and fresh fried Cod.
Another Maggie's favorite just off I-95 is Gene's Famous Seafood (also a simple clam shack) in Fair Haven, MA. Sippican likes it too.
