Chow near Sebago Lake
You're about a half hour from the coast, give or take 15 minutes. Harraseekett Lunch and Lobster, Freeport, is a classic lobster/seafood shack. Or hit Portland, plenty of choices. Portland Lobster Co. comes closest to lobster/seafood shack. For fancier, can't go wrong with either Street & Co. (seafood and only seafood) or Old Port Sea Grill. All three are in Old Port/Waterfront.
