The Big Deck

Sitting over the water, our big deck with rolling wooden bar, boasts stunning views of Mattituck Creek and the Osprey nests opposite. It’s a unique setting for lunch or dinner for up to 60 people, “ magic hour” cocktails, late-night plein air dance party, or an intimate wedding ceremony.

The Covered Porch

Get the best of both worlds on our covered and heated porch which can seat up to 30 for a private lunch or dinner or accommodate up to 40 guests for drinks and canapes. The porch space can link seamlessly with our interior restaurant by opening three sets of double doors to link inside and out.

The Interior Bar & Restaurant

Celebrate surrounded by history in our restaurant and bar. Our waterfront dining room is ideal for gathering a larger group for a sit-down lunch or dinner and combined with our covered porch space we can host up to 90 people. Two-hundred old wooden beams and the original mill wheel mechanism stands in the center of the bar room bringing unique charm.

The Osprey Room

The Old Mill Inn is made modern in our cedar-clad art-filled Osprey room located upstairs above the restaurant. With 180 degree water views, you’ll see the boats go by and feel like you’re hovering above the water. From a small private dinner for 10 people to a festive luncheon for up to 35, we love transforming this space in creative ways.

The Jetty

Sailing into Mattituck Creek is one way to arrive in style at The Old Mill Inn but you can also experience being this close to the water with lunch or dinner for up to 30 people on our private jetty.

Weddings & Rehearsal Dinners

A few times a year we offer the opportunity to take over our entire space for the ultimate celebration. The bride can arrive via yacht and the groomsmen by speedboat if they so desire. We can host an intimate ceremony on our jetty or big deck, followed by cocktails and local oysters and a sit-down lunch or dinner for up to 90 people–with the dancing can kick on under the stars or in our mahogany bar. We create custom menus with our Executive Chef Kyle Bloomer that make the most of the North Fork's seasonal farm produce. Cocktails (inspired by the couple) and are served alongside local and world wines.
