Seaside Grill

The waterfront main dining/full service restaurant is open for the 2023 season. Sipping margaritas by a on a sunny day right on the water…what could be better during the summer on Long Island? The Seaside Grill, located adjacent to the Hyatt Place East End & Resort Marina, is the newest seasonal hot spot to hit Long Island’s 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 brunch, lunch or dinner while sipping a cool drink either poolside or at our waterfront dining area.
