Graziano Lembo owns the Capri Caffe. He says his metal roll down shutters protect his restaurant from vandals and thieves.
"I know New York City's safe, but you can't be 100 percent sure," said Lembo.
But city councilman Peter Vallone says those gates encourage graffiti. He wants to require all new gates sold and installed in the city to be at least 70 percent see through.
"We can really make a difference in the cityscape of New York City. It will make it much more beautiful, much cleaner. There would be 80 percent less graffiti," said Vallone.
