UPDATE: Co-owner Tom Graziano has also released a statement, through FiPS:
"My name is Tom Graziano and I'm the owner of PSbklyn. I want to make it perfectly clear that this establishment is not for sale. Whoever put up this bogus and unfactual listing and rumor of our demise is totally unfounded. I also want to mention that I'm not getting a divorce. I'm happily married with two children(2yrs and 4yrs) and find this all to be very disheartening. We're thrilled to be a part of Park Slope and put a lot of effort into building an establishment we thought people would enjoy. So far so good. The business has grown beyond our wildest expectations. We are totally comitted and will be in Park Slope for many years to come.
UPDATE 2: When reached for comment, a representative from Lisiten Associates, who posted the listing, told me, "There was a mistake in the listing. It's being taken down and will go back up when it's corrected. This was all a mistake." He then hung up the phone. I'm not sure what kind of "mistake in the listing" he was referring to, as it clearly refers to PSbklyn ("they have a full supervised game room on the lower level"..., etc), even if it doesn't mention the restaurant by name. Either way, someone put a lot of effort into this.
THE THIRD AND FINAL UPDATE: The owners are just looking for a third partner, and the listing was posted without their consent and has been taken down.
