We are planning to combine a visit to one of the North Shore famed clam shacks with an afternoon visit to Salem, MA. Our goal is to have seafood for lunch as we are from the Midwest and we hope to find some tasty, local, fresh seafood. We are not wedded to either of those 3, but are looking for a recommendation on a clam roll of excellent value and quality in proximity to Salem. Any thoughts, hounds? Thanks!
