The wall is coming down at 631 Old Country Road. Greek Food Emporium, the family-run Greek grocery that has anchored Plainview's Greek pantry shopping since 2019, started construction on September 9 to take over the storefront next door, a project that will double the shop to about 3,000 square feet. The family expects the bigger store to be finished before Thanksgiving.

A Queens story that moved east

The Emporium began in Whitestone, Queens, about 14 years ago, where the Mavrou family, parents Maria and Konstantinos with their daughter Tenia and son Evan, built a following for products brought in directly from Greece. Six years in, with a customer base that increasingly drove in from Nassau, they opened the Plainview location in 2019 and became one of the few dedicated Greek groceries on Long Island proper.

Anyone who has been inside knows the current footprint works hard. Feta cut and sold by the pound. Barrels of olives. Frozen souvlakia, trays of homemade Greek desserts, and shelves of cookies, pastas, dips and chocolates that do not show up in a standard supermarket's international aisle. The store has a reputation for carrying whatever you came in for, and that reputation is precisely the problem the expansion solves: the family has been fielding constant requests for more, and there has been nowhere to put it.

What the extra space is for

The announcement, made on the store's own Instagram in early September and since picked up in the Greek-American press, sketches a bigger operation in three directions. More of what the store already does, meaning added shelving and freezer capacity for the imported staples. A broader European selection beyond the strictly Greek. And, still in the deciding stage, prepared hot food, which would move the Emporium from a pantry stop toward something closer to a daily lunch destination on one of Plainview's busiest commercial stretches.

There is also a quieter engine behind the project: shipping. The store sells nationwide online, and that side of the business has grown to the point where the physical shop and the packing operation were competing for the same square footage. Doubling the store buys room for both.

The corner it strengthens

Long Island's Greek food landscape is mostly restaurants, diners and the annual church festival circuit. Actual retail, the place you go for the ingredients rather than the finished plate, is thin, which is why the Plainview shop draws customers from well beyond its own zip code. A doubled Emporium consolidates that role. It is the kind of expansion that never gets a ribbon cutting from a chamber of commerce and matters more to daily life than most things that do.

What to watch for

Construction is underway now, with the family aiming to be finished ahead of Thanksgiving, which is not an accidental deadline for a store whose holiday season runs on custom dessert trays and party platters. The shop remains open through the work, and progress updates are landing on the store's Instagram at greekfoodemporium. If the timeline holds, Plainview goes into the holidays with twice as much Greece on Old Country Road, and the answer to where you find real galaktoboureko in Nassau County gets a little easier to give.
