The Forum Diner of Bay Shore: 52 Years, One Closing, and What Comes Next

ByPeter

You learn something about a diner the moment it closes. Not when it was full — full is easy to love. You learn something when the sign goes dark and the parking lot sits empty and the people who used to eat there start talking about it online like a person who died.

That’s what happened on August 7, 2022, at 315 West Main Street in Bay Shore. The Forum Diner served its last plate, locked its door after 52 years of business, and left a gap that two subsequent attempts still haven’t filled.

I think about closings like this more than most people do. I’ve been opening a diner every morning since 2000. I know what it costs — not just money, but the grinding accumulation of early mornings and late deposits and conversations with every kind of person who walks through a door. When a place like the Forum goes, it’s not just a business closing. It’s a whole ecosystem of habit and memory that gets quietly dismantled.

How It Started: A South Shore Institution Built by Immigrant Hands

The Forum Diner opened around 1970 on West Main Street in Bay Shore, planting itself on one of the South Shore’s most trafficked corridors. Bay Shore was a working town then — ferry traffic to Fire Island in the summers, year-round residents who needed a place to eat breakfast before 7 AM and didn’t want to spend a lot doing it.

The timing was not accidental. Long Island’s diner boom ran roughly parallel to its postwar suburban expansion, and Greek immigrant families were at the center of it. As Alexander Kitroeff, a professor of history at Haverford College who has studied the Greek connection to diners in America, has explained it: the restaurant business didn’t require strong English skills, and Greek families brought with them the concept of philoxenia — a hospitality that was not a marketing strategy but a cultural inheritance. Larry Samuel, author of Making Long Island: A History of Growth and the American Dream, has written that these immigrant owners “saw being an entrepreneur by owning your own business as their American dream.” The diner was their vehicle.

My father came from Greece and went to work in a restaurant. I know that story from the inside.

The Forum was built for the community it served — Bay Shore, Brightwaters, West Islip — and for decades it functioned the way any good diner functions: as a second living room that happened to have a menu. Regular customers came every single day. The staff knew their orders. Manager Matt Moraitis, who was there at the end, described it plainly: “This was always another home for people. Especially our regular customers we would see every single day. They were like our family.”

In September 2015, the diner passed to new ownership. The new team kept the name, kept the address, kept the fundamental contract: American comfort food, fair prices, open every day, no pretense. The Forum’s four-star Google rating and more than 660 reviews were testament to a place doing the job it was meant to do.

2020: The Floor Comes Out From Underneath

The pandemic hit every diner in America hard. The Forum was hit the way small places get hit — without the reserves that insulate larger operations from a sustained shock.

Moraitis described it in terms I recognize from talking to colleagues across Long Island: “It wasn’t even like it was a slow drop, the floor came out from underneath us.” Business fell roughly 35 percent during the state-imposed shutdowns and dining restrictions of 2020. The Forum applied for relief through the federal Restaurant Revitalization Fund, a COVID-era small business program — but the program ran out of money before their application was processed.

That outcome was common enough to be a pattern. The RRF distributed roughly $28.6 billion to more than 100,000 restaurants before funds were exhausted in 2021, but applications had exceeded available money by more than four to one. Many operators who needed it never got it.

The Forum kept going. And then inflation arrived.

The numbers Moraitis shared with reporters were not abstractions. A case of 30 dozen eggs went from approximately $45 to $120 — overnight, he said. Cooking oil climbed from $19 a gallon to $46. “Even with raising the prices on the menu, the math doesn’t add up,” he said. He also made a point that doesn’t get made loudly enough: this was happening everywhere. Small businesses were absorbing the cost while larger chains had the purchasing power and the margin to buffer it. The independent diner had neither.

The Forum announced its closing. It would serve its last customers on August 7, 2022 — a Saturday — with final service ending at 3 PM. In the days leading up to it, Moraitis made the kind of statement that strips away all the noise around business closings and gets to what actually happened: “I love the Bay Shore, Brightwaters, and West Islip area. I’m going to miss it so much. I have the absolute best employees that anybody could ask for.”

That’s not corporate language. That’s a man who built something with people he cared about, and couldn’t save it.

The Goodbye

The last day drew a crowd. Bay Shore, Brightwaters, and West Islip residents who had eaten there for decades came to say goodbye to booths they’d sat in their whole lives. Regulars who knew the staff by name. Customers like Frank Portelli, who told News 12 simply: “I love when you come, everyone is happy. They take care of you and the food is good.”

Before the doors closed, however, ownership reached out to Greater Long Island with an update: there were plans to reopen the space. No details. No timeline. Just an indication that 315 West Main Street was not necessarily finished as a restaurant.

That note of hope would matter — and then, in the way these things often go, it would get complicated.

The Next Chapter: BBD Bay Shore

Sometime after the Forum’s closing, a new concept opened at 315 West Main Street. BBD Bay Shore — Breakfast, Brunch, Dinner — moved into the space that had been the Forum’s home for more than five decades.

Early reviewers described it as a genuine departure from the Forum’s diner model. One reviewer described the menu as “a mix between the Toast restaurants and a diner,” with a broader, more contemporary set of options. The hours reflected a different operating philosophy — a morning-to-afternoon window on most days, with dinner service on Friday and Saturday evenings. The address was the same. The intent was different.

BBD brought energy and a following. But by mid-2025, according to Yelp records updated that September, BBD Bay Shore had also closed.

The address at 315 West Main Street now stands as a building that has housed two closings in three years — each one distinct, each one shaped by its own set of pressures, but both ultimately unable to outlast them.

What This Building Represents

Bay Shore is not a dying town. The restaurant scene along Main Street and the waterfront has continued to evolve — the Tap Room, Magnolias, Captain Bill’s, the newer wave of dining spots drawing people down to the Great South Bay. The town has development momentum, a revitalized downtown corridor, and ferry traffic that drives summer business.

Which is exactly why 315 West Main Street is such a pointed absence. This is not a vacant storefront in an economically depressed area. This is a high-traffic corner on a South Shore main drag that has now failed to hold two restaurants in succession. The question isn’t whether Bay Shore can support a restaurant at this address — it has supported them for half a century. The question is what kind of restaurant can survive the current cost structure at a location with the rents that West Main Street commands.

Long Island’s independent diner is under genuine structural pressure, and the Forum’s story is not unique. In Sayville, just a short drive down the Shore, both diners that once anchored the hamlet’s main street are gone — the Sea Crest Diner and the Sayville Modern Diner, which closed in 2015. The Peconic Bay Diner in Riverhead closed and eventually reopened under new ownership as Peconic Diner. The pattern repeats: a closure, a gap, sometimes a revival, often a different concept trying to fill a shape that was built for something else.

I wrote about this with the Hampton Bays Diner when it closed — another beloved South Shore institution that left a community without a gathering place it had relied on for generations. The Forum’s story is the same story, playing on a different block.

The complete picture of what this means for Long Island dining — from diners to fine dining — is something I tried to map out in The Complete Guide to Dining on Long Island’s North Shore. The Forum belongs in that map, even in closing. Maybe especially in closing.

What’s Next for the Address

As of this writing, 315 West Main Street in Bay Shore has no confirmed new tenant. Ownership indicated in 2022 that they intended to reopen the space — BBD was presumably that attempt, or the space passed to new operators who tried the same. Either way, the building is back at the beginning of that question.

What comes next at this address is genuinely unknown. Bay Shore has the foot traffic and the demographics to support a well-run restaurant at this location. But “well-run” in 2025 and 2026 means something different than it did when the Forum opened in 1970. Food costs are higher. Labor costs are higher. Rents on active commercial corridors have not come down. The operating margin that allowed a family to run a diner for 52 years and build something resembling a livelihood has compressed in ways that make the same model increasingly difficult to sustain.

Whether a new operator opens a diner, a brunch spot, a cocktail bar, or something that doesn’t have a category yet — the building will carry the weight of what was there before. That’s how it works with places that have been gathering spots for half a century. The booth might be different. The sign will be new. But the neighborhood will remember who used to sit there.

A Closing That Wasn’t Really About Food

The Forum Diner closed because eggs went from $45 a case to $120. Because rent didn’t stop during a pandemic. Because a government relief program ran out of money before it got to a diner in Bay Shore, New York.

Those are the facts. But what the regulars showed up to say goodbye to on August 7, 2022, wasn’t the eggs. It was the people who cooked them, and the years of mornings that became the texture of their lives.

That’s what a diner is. It’s not complicated, and it’s not small. It’s just easy to forget until it’s gone.
