About 369 Dune Road

Positioned on prestigious Dune Road, just moments from the Atlantic Ocean and the Shinnecock Inlet, 369 Dune Road presents a singular opportunity to acquire one of the Hamptons' most recognized waterfront destinations. Home to the iconic Sundays on the Bay, this fully operational restaurant and marina combines hospitality, marine infrastructure, and irreplaceable location in one exceptional offering. Set against panoramic sunset views over the bay, the restaurant features 118 indoor seats framed by expansive windows that capture the waterfront setting, along with a spacious outdoor deck offering an additional 77 seats and two full-service bars. The atmosphere is vibrant yet refined - a proven draw for locals, seasonal residents, and boating clientele alike. The marina is equally compelling, offering 30 deepwater slips accommodating vessels up to 90 feet, with direct Atlantic access via the Shinnecock Inlet - ideal for sportfishing yachts and luxury craft. The property includes a fuel dock with approximately 12,000 gallons of diesel and 10,000 gallons of gasoline storage capacity, a well-maintained bulkhead, and professional-grade marine infrastructure. Additional improvements include a ±2,000-square-foot accessory structure currently utilized as an ice house, providing flexibility for expanded marine or hospitality use. With its unmatched waterfront exposure, established reputation, and rare zoning profile, 369 Dune Road offers extraordinary potential for continued hospitality operations, marina expansion, or strategic waterfront redevelopment. Opportunities of this scale and visibility on Dune Road are exceptionally rare. This listing may include images that have been digitally altered or virtually staged.
