While there's much from maritime history that still resonates today, very little of it is edible, as 100yr-old fish is nasty. Finally take a gluttonous bite of Sag Harbor's seaside history, at The Bell & Anchor
From the buds who brought you longtime faves Fresno and the Beacon, Anchor offers panoramic views of Mill Creek Marina matched only by the handsomeness inside:
you white and sea-green/blue accents, wooden tables large & hearty enough for lobster feasts, and maritimey touches like a giant mounted fish head, and, umm... bells and anchors. Splice the mainbrace (or whatever) with nine wines, 10 bottled beers, and local taps pouring three Publick House brews and, awesomely, three vinos from the Fork; or get ready to really pitch with a classic Mai Tai, the ginger/dark rum Black Buoy, and their take on a Rum Runner using ginger beer and mint, aka the opposite of your condition after drinking all this stuff. Thirst slaked, there're starters like lobster cobb salad & smoked duck tacos (w/ spicy hoisin jam), and entrees including chili-accented Cioppino (w/ hake bolstering the requisite shrimp/ mussels/ calamari), and the grilled bone-in rib eye "Captain's Steak", which will have you looking more Brando's Kurtz than Bligh
Oh, and there's a whole section dedicated to lobster, which includes Surf & Turf, Thermidor (mustard, gruyere, cognac), and standard, clawed beauties available up to 2.5lbs, though the act of eating it will have both you and it looking pretty nasty.
