From a press release on Shake Shack's official website:
Danny Meyer’s Union Square Hospitality Group (USHG) is proud to announce it will open its second Brooklyn Shake Shack in Fall 2013. The new Shack will make its home at 170 Flatbush Avenue, just a three-pointer and slap shot away from Barclays Center—NYC’s exciting new entertainment destination and home of the NBA’s Brooklyn Nets and NHL’s New York Islanders (2015).
“Our second Brooklyn location will be directly across from the Barclays Center and plant us firmly within walking distance of several neighborhoods from Park Slope to Fort Greene,” said Randy Garutti, Shake Shack CEO. “New York City is our hometown, and the Shack will be the place where New Yorkers can come together to celebrate the best of Brooklyn’s thriving culture, sports and entertainment.”
170 Flatbush Avenue is directly across the street from Barclays on Flatbush, just south of Pacific Street.
Today is a great day in Brooklyn history.
