When W. Wells Watson opened a little ice cream shop just west of Hyannis in 1934, his location was the inspiration for a name. Recalling the first line of a favorite poem – “We face four seas / Four seas of azure blue” – he counted the Atlantic Ocean, Nantucket Sound, Buzzard’s Bay, and Cape Cod Bay, all of which surround the Cape, and he named his parlor Four Seas. Now overseen by Dick Warren, who bought the business in 1960 after working behind the counter a few years, the wood-sided building, which once had been a blacksmith’s shop, is burnished with age. The floor lists; and the waist-level, silver-topped freezers where ice cream is stored bear dents and dings from millions of scoops and milk-shake beakers. The snug interior decor of miscellaneous fish nets, nautical nick-nacks, souvenir T-shirts, and newspaper clippings has been called “hodgepodge Cod.”
