Maffei Pizza's grandma slice has long been celebrated as one of the best of its form in Manhattan. I had one recently, and I have to say, I wasn't feelin' it. It's always easy to say, "Maybe they were off that day," but Maffei cranks through these slices day in, day out—it was flying out of the pan when I visited just before 1 p.m. Which is to say that they should have things down there. I would not revisit nor could I recommend.
