I have been eating calamari like there's no tomorrow of late; some of the places I've recently had it include the Dock and Dine in Old Saybrook, CT; Louie's Seafood in Raynham, MA; and The Lobster Tale in Brant Rock (a part of Marshfield, MA).
Though the restaurants above all have good calamari (especially The Lobster Tale), I would love to find some other places that have it. If you know of any, please post a comment here, or let me know through the Boston's Hidden Restaurants forum.. Thanks!
