New Yorkers speak fondly -- and this year nostalgically -- of road trips north along the clam belt , with stops for baskets of fried bellies in some of New England 's prettiest towns : at Bob 's Clam Hut in Kittery , Me . , for instance ; in Massachusetts at the Clam Box of Ipswich or the slightly rougher Kellys at Revere Beach ; in Connecticut at the Black Pearl in Essex , or the Clam Castle in Madison .
