It's not quite the scandal that Chris Christie has on his plate, but Mayor de Blasio is turning heads, and maybe some stomachs, with how he eats a staple of New York cuisine.
It's called Goodfellas Pizza, and at the Staten Island landmark, there's an unspoken code for how to eat its award-winning pies.
"All New Yorkers eat their pizza with their hands," said Scot Cosentino of Goodfellas Pizza.
Yet there was New York's new mayor, devouring a smoking slice with, mamma mia, a knife and fork.
He eventually switched to hands, but in starting with cutlery, the mayor was just about alone among the Staten Islanders he invited for pizza and conversation.
Even a 103-year old dining companion snacked hand to mouth.
Michael Gallo said he isn't put off. He's just pleased that the mayor called him during the recent cold snap to check in.
"It doesn't bother me," Gallo said. "I just was happy that he called me and he had took time out to call me."
While de Blasio draws kudos for his political policies, some are spitting out their spumoni at how he eats.
"It really calls into question if he's a real New Yorker," said Ed Levine of Serious Eats. "It's like, come on. You can't eat pizza with a knife and fork if you're a real New Yorker."
De Blasio is known for his fastidious eating habits, particularly Italian food.
Cannolis are so beloved, he substituted them for a wedding cake years ago.
Espresso is also to be imbibed from small cups only.
But pizza with a fork?
"Very important question," de Blasio said. "In my ancestral homeland, it is more typical to eat with a fork and a knife, and so I have been in Italy a lot, and I picked up the habit for certain types of pizzas. So when you have a pizza like this, it had a lot on it."
De Blasio also munched on meatier topics, such as the lingering effects of Hurricane Sandy and complaints that the Health Department is unfair to small businesses.
De Blasio lost Staten Island by nine points in November's election to Republican Joseph Lhota. On Friday, Republicans joined him at the pizza event.
The consensus was gratitude that the mayor came to the island, despite differences in party and pizza protocol.
