Sipping margaritas by a sparkling pool on a sunny day next to the water…what could be better during the summer on Long Island? The Seaside Grill, located behind the Hyatt Place Long Island / East End. With views of the lush scenery of the Peconic River, along with the boats dotting the shore at Treasure Cove Resort Marina, patrons can enjoy lunch or sip a cool drink under spa blue umbrellas.
