The BlackSheep, a scratch-kitchen American fusion restaurant on Route 25A in Miller Place, has shut its doors after operating for slightly longer than a year, and a sign advertising the restaurant for sale is now posted outside the Park Avenue Plaza storefront. Tables remain set up inside, with salt, pepper and ketchup still sitting out, as if service could resume at any moment.
The closure was first reported by Greater Long Island, whose reporter Brian Harmon found the restaurant had been closed for a couple of weeks and located next to a nail salon at 465 Route 25A. Owner Jon Kopstein, who lives in Port Jefferson, opened The BlackSheep in June 2025 after previously working as a sous chef at Maggie's Eatery, the concept that occupied the same space before him. The cause of the closure remains unclear, and The BlackSheep's Instagram account replied to inquiries only by confirming the restaurant was closed and apologizing for the inconvenience, per the account.
A restaurant-for-sale sign now posted at the location lists broker Bob Damon, who can be reached at 516.551.3302. The BlackSheep's decor had leaned into its name, featuring a black sheep art theme that Kopstein built around the community and local school districts.
A Storefront With a Revolving Door
The BlackSheep's run adds another chapter to a stretch of rapid turnover at 465 Route 25A. The space previously housed Long Island Mills Coffee Brewery and later Crazy Crepe Cafe, a regional creperie chain that still operates locations in Selden, Smithtown and Lake Ronkonkoma, according to Greater Long Island.
Maggie's Eatery took over next, debuting in January 2023 with a modern American takeout menu that included lobster tacos, seared tuna bowls and dry-rub wings dubbed “Smack Ya Mama.” The concept was launched by East Hampton chef Tyler Hannibal, who had spent a decade as executive chef at Bostwick's Chowder House before striking out on his own, per Greater Long Island's earlier coverage. Maggie's closed after a short run in the space in April 2025, just months before Kopstein opened The BlackSheep in the same bay.
Menu Built on Comfort With a Twist
Kopstein brought more than a decade of culinary experience across Long Island kitchens, catering halls and private clubs to The BlackSheep, his first independent restaurant, according to Greater Long Island's earlier reporting on the opening. He designed a scratch-cooked fusion menu anchored by dishes like “Mah's Mac and Cheese” topped with garlic herb crumbs and the “Dockside Deviant,” a panko-sesame crusted salmon cake served over seasoned fried rice.
The restaurant had civic backing at its launch. Town of Brookhaven Councilwoman Jane Bonner and local business leaders held a ribbon-cutting ceremony for The BlackSheep on June 25, 2025, presenting Kopstein and his wife Ashley with a Town Certificate of Congratulations, according to the Town of Brookhaven. Kopstein had established the business as a family venture alongside Ashley and their children.
Wider Pressures on Independent Dining
The BlackSheep's closure lands amid a punishing stretch for independent restaurants across the region. Commercial data cited by RestaurantData shows the New York-Northern New Jersey-Long Island metropolitan area recorded 491 restaurant closures in the first half of 2026, with quick-service and casual dining spots accounting for more than 86% of those shutdowns. A New York State Restaurant Association survey separately found that 91% of participating operators statewide reported lower profitability compared to pre-pandemic baselines.
Those pressures have hit Suffolk County dining spots particularly hard, as independent operators contend with rising commercial lease costs, inflation and growing competition from fast-casual chains and delivery platforms, according to Patch. Meanwhile, national chains are still expanding along the same Route 25A corridor: Mister Softee recently secured plans for a permanent storefront at the nearby Aliano Shopping Center, as Hoodline previously reported.
Whether the Park Avenue Plaza bay's lease terms or the site's physical layout have contributed to the string of short-lived tenants remains an open question. For now, the space that once served lobster tacos, dry-rub wings and mac and cheese with garlic herb crumbs sits empty, its tables still set, waiting for its next occupant.
