It would be difficult to get much closer to the fish than at Westlake Fish House, right on the dock at Westlake Marina in Montauk. Most afternoons, you can see charter boat mates filleting striped bass right outside the restaurant windows, with all that entails. It is a pretty good way to keep the kids entertained while waiting for a table. Westlake has lunch options heavy on seafood, including fish tacos and an inventive swordfish B.L.T. Dinner choices include monkfish with chorizo, kale, and white beans, roast tilefish, salmon, and hanger steak.
