Restaurants mining space for cash as costs soar

If you can’t sell them enough food and booze, try marketing the toilet.

Slammed by sky-high costs for food, labor and rent, New York’s bars, restaurants and nightclubs have begun using a growing crop of third-party apps and services to rent out their dining rooms, coat check areas and even their bathrooms to make extra cash.

Luluapp — a mobile app that, for a fee, promises to direct tourists and others with bloated bladders to the nearest available bathroom — says it has already signed up more than 100 New York restaurants and bars ahead of its summer launch.

“Instead of paying a lot of money for a Facebook or Yelp ad, we let restaurants promote a free drink or discount to our users” after they use the facilities, Luluapp boss Paolo Cogliati told The Post.

Luluapp generates a digital “bathroom pass,” charging anywhere from 99 cents to duck into a pizza dive to $5 for a swanky bathroom that offers lotions, super-private stalls and high-end hand towels. The restaurants get 65 percent of the fee.

“Restaurants do want to hear our pitch because it’s just so weird,” Cogliati says.

He declined to name any of the restaurants he’s working with, but Burak Karacam, owner of the swanky Pera Mediterranean Brasserie near Grand Central Terminal, said he got pitched by Luluapp and passed on the idea.

Instead, he decided to sign on with BAGBNB, a Romebased luggage storage startup that claims to work with bars and restaurants in 60 cities worldwide, including 26 venues in the Big Apple.

BAGBNB, which splits its $6, per-bag fee with restaurants, also has expanded by offering commissions to tour operators, Airbnb hosts and hotels for suggesting its services to their lodgers.

“It can be a little hectic in the morning when you have 10 people lined up ready to drop off their bags,” said Chelsea Feldcher, a manager at Pennsylvania 6, a restaurant near Penn Station that started using BAGBNB a few months go. “But obviously any extra revenue is great for us and we are introducing new people to the restaurant.”

Pennsylvania 6 currently pulls in about $2,000 a month from storing people’s bags for a few hours or for the day, ac- cording to Feldcher. About 25 percent of those customers end up grabbing a drink or meal at the eatery before they catch their train, she says.

Meanwhile KettleSpace, a six-month-old startup, has inked about half a dozen deals with restaurants and bars to open their dining rooms to freelancers and entrepreneurs during off-hours.

It charges its laptop-toting clientele $25 for 10 hours to $99 a month for unlimited access to use the restaurant spaces, where coffee, snacks and meals are sometimes part of the deal. By comparison, WeWork’s least expensive plan in New York costs $220 a month.

“KettleSpace is the cheapest alternative that I found,” said Bradley Orego, a graphic designer and professional dancer who was working at P.S. Kitchen, a restaurant off Times Square, on a recent afternoon.

“It’s newfound money for us,” said nightclub owner Ravi Patel, whose Hotel Chantelle recently opened up its rooftop lounge in the Lower East Side to KettleSpace workers.

“This has the potential to reach $3,000 to $5,000 a week for us, which could slash my rent by up to 30 percent,” Patel said.

Hotel Chantelle is not open to the public for lunch, but it’s offering light fare to KettleSpace members. “Our kitchen staff is prepping for the evening anyway,” Patel said.
