25 Years, One Family, Countless Plates

25 Years, One Family, Countless Plates

Seaport Diner started as a family's promise to Port Jefferson: real food, cooked with care, served by people who actually know your name. Twenty-five years later, that promise hasn't changed — we've just gotten better at keeping it, one plate of home fries at a time.

From the Griddle to the Skillet

From the Griddle to the Skillet

We believe a diner menu should have no limits, that's why you'll find Nutella banana pancakes next to a Greek gyro platter, and smoked brisket a few pages from stuffed shrimp. Everything's made fresh to order, because shortcuts don't belong on a plate with our name on it.

Right Where Nesconset Highway Meets Home

Right Where Nesconset Highway Meets Home

Tucked into Port Jefferson Station on Nesconset Highway, Seaport Diner has the kind of low-key, welcoming feel that makes strangers into regulars. Pull up any hour we're open and you'll find booths full of neighbors, families, and folks who've been coming back for decades.
