My little boy has not yet had pizza. I'd love to have introduce him to a good slice. Any suggestions? I've heard good things about John's on Bleecker but they don't sell individual slices. I don't mind going for a whole pie but a slice place would be good too. It could be a place that delivers but he and I are doing bonding evenings out so a baby-friendly place not too far (from Wash. Sq. Vill.) would be great as well.
