Dining Outside the Home: Blue Lobster Grille in Rockport, Massachusetts! Some days it pays off to forego classic menu items and roll with the specialty of the gourmet chef, especially when it comes to seafood. Today’s feature: Stuffed Haddock in a creamy butter sauce. Agnoldo Oliveira takes his reputation seriously. Never mind that the Blue Lobster Grille affords the perfect vantage point of Rockport’s iconic Motif No. 1 as well as daily activity around Dock Square. You’ll find yourself trying not to stare at the heaping plates of those customers around you. It’s that good!
