Cafe Pizzaiolo and its spin offs. They just opened in cameron run, the are at Fairlington, and the original location is in Crystal City at 23d and Eads (just off Rte 1). they do NY style and Neapolitan.
I've not tried Petes yet, so I can't say if they have New Haven style right, but I trust the Cat and the Frau.
I used to love the beer delivery, Tuto had the best pizza on 23rd before they went under
