Toys “R” Us, the chain that bills itself as the “biggest toy store there is,” has just opened a temporary, pop-up store in the decidedly small-scale and still old-world Polish neighborhood of Greenpoint, Brooklyn.

The new store is part of a blizzard of 90 pop-up stores that the toy giant has opened around the nation in the last year, including four in Brooklyn alone. However, it’s one thing to open a chain store outlet on Jay Street in Brooklyn, where the new Toys “R” Us is a stone’s throw from a brightly lit Dunkin’ Donuts, a Duane Reade and a Pizza Hut, among other national brands. It’s another matter entirely to open one in an area where the bulk of the shops are independently owned, places like beauty store Zilko and candy store Slodycze Wedel. Or is it?

Noel Caban, a CB Richard Ellis broker who has done several deals in the area, says that the retail strip along Manhattan Avenue is becoming increasingly attractive to big chains.

“I’m seeing more national tenants,” he says. “There’s enough variety to host national, local and regional tenants, and everyone benefits.”

In fact, the most surprising thing about the new Toys “R” Us at 861 Manhattan Ave. is how few objections it’s drawn in the area. Part of the explanation may be that the outlet is a mere 5,000 square feet, a tiny fraction of the chain’s 110,000-square-foot Times Square flagship, and that it will only be around for four months.

The biggest objection has centered on the building itself: a decrepit two-story structure that many insist is an eyesore that badly needs not a pop-up but a major rehab.

“I’m a little disgusted,” says Robert Paskucki, owner of Wizard Electroland at 863 Manhattan Ave. “They didn’t replace the ceiling tiles, and they didn’t even paint anything.”

Mr. Paskucki ought to know. Before moving, his store occupied the spot for a dozen years. He insists that the interior has fallen into disarray since he moved out in April.

Sources say that Toys “R” Us is working with the landlord to spruce up the space, although upgrades may be moot, as the shop will only be around through the end of the Christmas season.

One person who isn’t fazed by the new arrival is Herman Hernandez, who along with his wife, Nancy, has owned the nearly 30-year-old Greenpoint Toy Center just down the street at 738 Manhattan Ave. for the past six years.

“I’m really not too upset about them opening there,” he says. “I sell a lot of different things than they do.”

His wife mentions their shop’s extensive offering of high-end toy train sets and educational toys, not to mention Corolle and Gotz-brand dolls-none of which are found on the shelves of their new rival.

Customer loyalty also allows the Hernandezes to sleep just a little easier. Several of their customers have begun e-mail campaigns asking friends not to go to Toys “R” Us, an effort Mr. Hernandez admits he welcomes. At the end of the day, though, he has one major consolation: time.

“Sure, it will it knock a couple dollars off my sales,” he says. “But they won’t be there for very long.”
