    A Wedding Experience That’s Uniquely Yours

    Your wedding should feel like it could only be yours. At Atlantis Banquets & Events, couples can choose the timeless elegance of the Sea Star Ballroom, with expansive windows overlooking the Peconic River, or create an unforgettable celebration inside the Long Island Aquarium, surrounded by dramatic exhibits and unexpected spaces your guests will be talking about long after the last dance. From waterfront ceremonies and cocktail hours to exceptional cuisine and a fully curated wedding experience, our Riverhead campus brings everything together in one distinctive destination, giving you the flexibility to celebrate traditionally, do something completely unexpected, or create a wedding that offers a little of both.
