Someone told me long ago that Escape from New York Pizza near Haight Ashbury had real New York Pizza. Quite simply, no. It is not.
Arinell Pizza at 16th & Valencia, they make a New York slice. I was in the city (I hear that San Franciscans gingerly call SF “the city” but folks in LA know that “the city” is New York) in October and had Rosa’s Pizza in Penn Station. The two compare very well.
