A distinctive opportunity to acquire an established seasonal business on Great Diamond Island. Located on Diamond Cove within the Fort McKinley Historic District, Crown Jewel has been a treasured Casco Bay destination since opening in 2018, earning national recognition from The Wall Street Journal, The Boston Globe, Cond Nast Traveler, and other notable publications. Serving creative cocktails and a unique menu to islanders, boaters, and visitors throughout the summer season, the fully remodeled restaurant and bar accommodates lunch and dinner service, takeout, private events, and catered meals. At the back of the restaurant, a charming retail area pays homage to the building's original use as a general store, with coffee, baked goods, candy, clothing, cocktails to go, and other daily provisions. A wraparound deck provides outdoor seating for eight and a drink rail for waiting guests, while the intimate dining room accommodates 30, with additional seating at the bar and chef's counter. The open-concept layout includes a full bar and well-equipped kitchen with a six-burner gas stove, grill, fryer, oven, two refrigerators, and a large freezer. A separate back kitchen provides efficient food preparation and dishwashing areas with ample overhead storage. All furnishings, barware, lighting, equipment, and serving ware convey with the sale, along with a golf cart used to transport goods from the ferry to the restaurant. With an established presence in Diamond Cove and the infrastructure in place for continued operation, Crown Jewel presents the opportunity to carry forward a successful seasonal business or bring a new concept to this unique island setting.
