I still have yet to taste a pizza as good as the ones made by Delfina outside of Naples, Italy. And believe me, I've tried most pizza spots everywhere. The only other restaurant that hangs with Delfina is Roberta's in Brooklyn. When I lived on Guerrero in SF, I ate at the 18th Street location weekly. On this particular visit to San Francisco, I went to their California Street location.
And ordered my usual, margherita. Consistency consistently. Buon appetito!
