A new billboard has gone up on top of the building that will next be home to Shake Shack, on the south side of Flatbush Avenue directly across the street from the Barclays Center, advertising Brooklyn SkyBox, "The ultimate sports viewing experience," coming soon.
There's a Twitter handle set up, and the concept already seems to be pretty fleshed out. Looks like it'll be a "stadium inspired restaurant that features sports viewing, roof top lounge, fine dining, food concessions, event rentals, arcades and games," according to the description, and apparently they've already worked out a partnership with Pepsi. It also appears as if it's owned by Drummond & Drummond LLC, a management and holding company.
This place looks like it's a massive undertaking, but neither the Twitter feed nor Facebook page gives away the exact address. I've called the number on the Twitter page and left a message; I'll update if I receive any more info.
