Right next door to the Long Island Aquarium, Jerry and the Mermaid is a great choice for families to relax over dinner after their Riverhead adventures. Owned and operated by chef Jerry Dicecco, this casual, family-friendly spot serves lunch and dinner daily and has an extensive menu packed with selections from both land and sea. Settle in on the comfortable patio overlooking the Peconic River and enjoy some fresh seafood and a glass of Long Island wine. An affordable children’s menu is available as well.
