Lobster Dinner in Triangle?
Again: Squids is the place. In fact, some evening early in the week, I think mondays but call them, is lobster night when lobsters are cheaper.
Plus they have the raw oysters, clams, shrimp cocktail, bisque, or other accompaniments to lobster that you may desire.
And ask for a big one, it is a horrible calumny that smaller lobsters are better.
Try Squid's in Chapel Hill. I've had "traditional" lobster dinners there. Their menu on line has: "Lobster Dinner - 1.25 pound live Maine lobster, steamed and served with drawn butter, mashed potatoes, and sauteed asparagus. Market price
Larger lobsters are available on request". I buy live lobsters from them a few times a year, and the ones I've taken away are very lively, unlike Fishmongers in Durham.
