La Rossa enters scene in Soho

Well-known Italian pizza chef Stefano Callegari will open his first New York pizzeria in Soho next month.

La Rossa, at 267 Lafayette St., at Prince Street, will have 32 seats and serve Romanstyle pizza al taglio — what New Yorkers call pizza by the square slice — as well as the more traditional round pizza.

Callegari has eight restaurants in Rome as well as locations in Florence and Milan — and an unusual introduction to the pizzeria business. Before Callegari became a restaurateur, he worked as a flight attendant for more than 10 years. After more than 100 trips to Naples, where he indulged in the “art and science” of pizza making, he came up with his own recipes.

The upscale space will offer a selection of artisanal wines and beers offered by the bottle and glass. It will also serve Italian-style breakfast and have outdoor seating.
