The little red drive-thru at 2257 Wantagh Avenue is coming back to life, and this Saturday it wants to buy you a coffee. Wantagh Dairy Mart, the new operation moving into the barn-shaped building with the lighthouse tower, is handing out a free 16-ounce hot or cold drink at the window on Saturday, September 12, from 11 a.m. to 2 p.m. The pitch, per the signs in its own windows: come try the coffee menu and tell them what you think before the real opening.

For a building this small, the paper trail behind it has been moving fast. Wantagh Dairy Mart LLC organized as a company over the summer, held open interviews at the store on September 8, and on September 10 filed with the New York State Liquor Authority for a grocery-store beer license at the address. That filing is how most Long Island convenience stores get the cooler in the back corner, and it usually lands in the final stretch before a door opens.

A format Long Island grew up on

The building itself is the story for anyone who has driven Wantagh Avenue for a few decades. It is a tiny footprint on a quarter-acre lot, built around a single idea that once dotted the Island: you pull up, a window slides open, and milk, eggs, bread and coffee come out to the car. Most recently it operated as Lighthouse Dairy Mart, a name that matched the little white-windowed tower rising off the roof. Now the whole structure has been repainted barn red with fresh white trim, an American flag out front, and new signage promising express coffee pickup, online ordering, groceries and cold cuts at the window.

The new owners are leaning into the history rather than away from it. The logo stamped on their cups and window decals reads established 2026, rooted in tradition, and pictures a red barn beside a lighthouse, which reads as a nod to both the building's tower and the shorefront a mile down the avenue. The name itself keeps the Dairy Mart half of the sign that was already there.

If the formula sounds familiar this week, it should. The drive-thru dairy store, the format that Dairy Barn ran at dozens of corners across Nassau and Suffolk for half a century, is suddenly having a Long Island moment. Coffee Barn, which grew out of a former Dairy Barn building in Merrick, opens its second location in Albertson on September 17. Wantagh's revival is its own business with its own owners, but the bet is the same one: Long Islanders never stopped wanting to buy their morning essentials without leaving the car, and they carry real affection for the little buildings that once did it.

Coffee first, then the rest

The menu boards that have gone up at the window suggest coffee is meant to be the draw rather than an afterthought. Alongside the basics there are vanilla, salted caramel and apple orchard lattes, an iced brown sugar espresso, a house cold brew, a pumpkin sweet cream cold brew, peach green tea, and an espresso-spiked hot chocolate. That is a fall lineup a chain coffee shop would recognize, being poured out of a building the size of a two-car garage.

Around the coffee, the signage and the license application sketch the rest: groceries, cold cuts, packaged goods, and, if the SLA application is granted, beer. Orders will be available online for express pickup at the window.

What Saturday actually is

Saturday's giveaway is not the grand opening. The store's own channels still say coming soon, and no opening date has been announced. What Saturday is, is a shakedown run: free drinks from 11 to 2, in exchange for honest feedback on the coffee before the menu is locked in. For a business whose whole model depends on being someone's daily habit, letting the neighborhood taste-test the coffee first is a shrewd way to start.

The hiring push is running on the same timeline. The marquee out front spent last week advertising open interviews, and the store is looking for full-time and part-time drive-thru crew for evenings and weekends.

For Wantagh, the practical takeaway is simple. The odd, charming little building that has anchored that stretch of Wantagh Avenue is not being torn down for something bigger, it is being polished up to do the job it was built for. And for one Saturday afternoon, finding out what the new tenant is about costs nothing more than pulling up to the window.
