We’re skeptical of this ambitious claim for a few reasons, but the Daily News is reports today about a group that plans to open what would be the city’s largest flea market in Coney Island soon for the 2011 season, with “over 100,000 square feet of shoppers delight.” Officials with the market/carnival — named BK Festival — wouldn’t respond to the newspapers questions, but the paper quoted several vendors who said they were considering moving to the Coney Island space once it opens. It’s not clear where they would set up (perhaps in that pictured big empty space?), and the teaser website Brownstoner found has been taken down already. So we’ll believe it when we see it. 100,000 square feet, btw, is the size of your average Walmart.
