A polite restaurant with a full menu that ranges from tapas to brownie turtle hot fudge sundaes, Scott’s Harbor Grill is worth putting in the little black book for its excellent lake fish. Lemon pepper whitefish, which the menu says is procured in Naubinway, Michigan, is soft-fleshed, pure white, perfectly complemented by the butter and wine and lemon-pepper dressing in which it’s cooked. We are especially fond of the Canadian walleye this kitchen makes. Nothing could be simpler: a big hunk of char-broiled filet seasoned with only lemon and butter. Its meat is dense, moist, and ineffably flavorful with a delicacy that is a world apart from the seafaring taste of ocean fish.
