Make a reservation and enjoy one more evening together by the water.

We're still serving up flavor here in Diamond Cove, crisp chilled asparagus, toasted almonds, shaved Parmesan, aged balsamic, and brown butter aioli come together in a dish that feels right at home between sunny afternoons and cooler evenings.

Make a reservation and savor the season while it lasts.

The best kind of waterfront escape comes with a harbor view and a cocktail close by. At Cocktail Cove, boaters can drop anchor, settle in, and enjoy drinks delivered right to their spot on the bay.
