Giorgio Zocco, the head barber at Carroll Gardens' Sal's Hairstylists—and known to everyone as "Sal"—died on April 4 at the age of 70. Many thought the old Smith Street space would be converted into something chic and urbane. And it has. But it's still a barber shop. It's called Persons of Interest, which is one of the most unfortunately pretentious shop names I've ever heard. But the space, while slick, is respectful of Zocco's memory. The old barber pole remains outside, as does the wall-size mural of some Italian seascape in the back—probably Pozzallo, Sicily, where Zocco was born. $40 a cut. I may give it a try, if only to take in that mural one more time.
