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 adjacent to the Hyatt Place Long Island/East End, 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 lunch or sip a cool drink under spa blue umbrellas. Full food service is also offered.


Choose from an assortment of specialty cocktails, including rum runners, daiquiris, or our signature Seaside Sangria, or enjoy something from the kitchen, including calamari, crab cakes, homemade pommes frites, fish + shrimp tacos, and more.
