Along with having one of the more interesting names we've heard, Persons of Interest also serves up some of the best haircuts in Williamsburg. This relaxed shop welcomes both appointments and walk-ins with quality tunes, a healthy stack of interesting reading material, and a good choice of beverages: seltzer, Coke, or Brooklyn Lager. The prices are reasonable, and the list of services includes everything a guy needs — cuts, clean ups, beard trims, shaves, and a combo cut/shave — and nothing he doesn't.
