Fried seafood on the waterfront defines summertime — at least once in a season. You can forget your dream of squeezing into a bikini after a fried bucket of seafood at the Clam Shack, a teeny operation in Falmouth. But the clams, scallops, and freshly snagged fish are all so good, how can you say no? Especially when you learn that a father and son duo (Jim and Jim Limberakis) have run this popular joint since 1962. They still draw devotees. Abandon all hope of scoring a seat inside and retreat to the back deck to watch resident seagulls and boats sail past.
