Indeed, at least eight new bars and restaurants have popped up on the Brooklyn boulevard in the last two years alone.(NY Post map adapted by No Land Grab)
Obviously the "blight" on the AY site above Dean Street west of Vanderbilt is not deterring development.
And on Sixth Avenue
From the Brooklyn Paper:
In a town full of mediocre burgers, the discovery of a new favorite is somewhat akin to waiting less than an eternity for the G train — a rare occasion. Enter the Agoulou, the West Indian-style burger at three-week-old French-Guadeloupian eatery Kaz An Nou in Prospect Heights and a very possible new favorite.The restaurant is at 53 Sixth Avenue, just below Dean Street, the border of the Atlantic Yards footprint.
Again, the "blight" doesn't seem to be much of a deterrent.
