At the Waverly Inn, a hot spot for boldface names in Greenwich Village, bottled water is being nixed in about two months.

It’s already 86’d at Il Buco, Mario Batali’s Del Posto, Gemma in the Bowery Hotel, Bobo, Gusto Organics and Broadway East.

Even the Park Slope Food-Co-op will vote later this month on banning bottled water from their shelves and hawking filters and reusable thermoses instead.

These green-thinking foodies are faced with the fact that it takes 41 million barrels of oil a year to make, transport and refrigerate water bottles, and that a crushing 30 million plastic water containers end up in landfills each day.

But both plastic and glass bottles are going.

Instead, places like The Waverly Inn will begin offering politically correct pints on the menu.

“It just seems simple and painless,” said Sean MacPherson, an owner of Waverly Inn and Gemma.

Waverly will serve flat tap water for free, and charge $5 per glass for its homemade, specially treated sparkling water from the tap — as MacPherson does at Gemma.

“I don’t see why we wouldn’t do it,” MacPherson said. “It helps out the environment and tastes good.”

At Per Se, a filtration system was installed in January. Sales of the house brand have risen while sales of bottled water — which continue for now — have dropped off.

Growth of bottled-water sales was just 6 percent last year, down from 9 percent in 2006, while sales of filtration and purification systems are skyrocketing. Filter maker Brita reported double-digit sales growth last year, and competitor Natura Water’s sales surged more than 100 percent in the last six months.

The Marriott Downtown has also jumped on the bandwagon. The hotel installed a filtration system in its Roy’s restaurant but still offers bottled water for now. By summer, the filtration system will be hotel-wide.

“I’m fascinated with the supernatural,” says Sal Cicconi, 27.

Cicconi, along with Sergio Ocasio, 20, and Samantha Ramirez, 18, have plastered Brooklyn offering their services for just $20 an hour.

Their business plan is a bit unorthodox, but then again, so are they.

“When I was a kid, I had this ability, this gift,” Cicconi said in an interview in the trio’s East New York apartment. “When I was 10 years old, I started to see things — spirits and ghosts.”

The three, who call themselves Brooklyn Ghost Investigations, are otherwise unemployed.

A movie screen hung in front of a single blue 1965 Ford Falcon convertible. A romantic starry sky — actually tiny light clusters peeking through sheer black fabric — stretched across to the side.

“Hey, can we make out?” he asked aloud, eliciting a giggle from Mr. Kushner’s wife and a gag from their 18-year-old daughter.

Stuffed inside the 250-square-foot space is DRV-IN, Manhattan’s only (and quite possibly the world’s smallest) drive-in cinema. The vintage Ford, parked in front of a 102-inch screen, has a shiny red interior that seats up to six cinephiles.

Michael McMahon (D-North Shore) yesterday introduced a bill that would limit the size of such signs throughout the city.

Claiming the signs have a “detrimental effect on the aesthetic value of New York City’s residential neighborhoods,” the proposed legislation limits “for sale” signs on residential properties to a maximum size of 4 square feet.

“While traveling in my district, I have noticed what seems to be an explosion in the size of real estate signs on front lawns to a degree that is practically obnoxious,” McMahon said in a prepared statement. “Real estate companies have the right to advertise, but let’s keep it tasteful.”

The measure is also catching flak from one Realtor, who said his signs must be large enough to attract buyers.
