Why People Love It: Because there's nothing like a New York slice (it's an NYC food icon, after all!), and Ray's may be the name most associated with the institution. There are Ray's all around the city, waiting to dish out a hot and gooey piece of pepperoni at pretty much any time of day.
Why It's Overrated: It's impossible to navigate the trove of "Ray's Pizza" available in the city these days. You have to be a very savvy pie-lover to figure out the difference between places like Famous Ray's, Famous Original Ray's and just plain Ray's, as many second-rate pizza joints have used the moniker to piggyback on the success of the name. At many of the locations, you'll have to sop the grease off your slice with a paper towel (or three). In the age of wood-burning ovens and artisanal pies, New York Pizza is evolving. Either get it from a stellar slice shop like Joe's or try the upscale versions from a joint like Co.
