YouTube superstars Nelk Boys to open bar with Miami mogul David Grutman

Miami mogul David Grutman seems to have finally got himself a lemon after he bought the Art Deco building for some $10 million

Spent four years turning it into a complex with three restaurants. And then all three of them shut down within a year.

The trio of spots — an upscale version of a classic ’50s diner, Winker’s, a sweets store called Tooth Fairy and trendy Asian-fusion place Sushi Fly Chicken

But the one-time rubber emporium quickly began to look a little tired. Winker’s and Tooth Fairy shut up shop less than 60 days later.

But insiders tell that they’re not actually boarded up — it’s just that there is once again construction going on behind screens

It’ll be the first time that the prank-happy group — which boasts a stunning 7.4 million followers on YouTube — has had its own brick-and-mortar bar to sling its popular bubbly booze.
