@kahlenz, the fierce debate is not over which city has the best pizza. Even New Yorkers and Chicagoans, if they're being honest, agree it's New Haven. The debate is about which ("apizza") place makes the best pie.
For the record, I've had most of them and they're ALL amazing. Sally's, Pepe's, Modern, and so on. Heck, I even like Ernie's. Then we get to West Haven, North Haven (which has had some stellar places in the past), and beyond.... Now I'm hungry!
