When out-of-towners think of grabbing a lobster roll in Boston, they probably envision a tiny seafood shack at the end of a fish processing plant, served by people who look like the Gorton’s Fisherman. Take them to Yankee Lobster for lunch and watch their dreams come true. We rank this our eighth-best lobster roll in Boston, but it’s one of the rare Seaport dining experiences that doesn’t feel like you’re eating in an outdoor mall. Instead, it’s a charming, bare-bones spot with counter service and picnic tables to perch on while housing an excellent lobster roll.
