I was on Nantucket on Monday and had fried clams at Sayles, a seafood market by the boatyard and for $11. I had an appetizer portion of fried clams which was plentiful and delicious. Also to be had there are Nantucket bay scallops, lobster and steamers. Though it is not a restaurant, they do mostly take-out, there are a few tables on the porch for eating. This is my spot when I'm on Nantucket.
