In the amped-up war of commerce and 75-cent pizza on the Avenue of the Americas in Midtown, a perilous moment is approaching. Circumstances suggest that ravenous New Yorkers might soon witness 50-cent pizza, 25-cent pizza or, yes, free pizza.

It is that caustic. Neither side is willing to yield an inch — or a cent. Escalation seems imminent.

As so often happens in twisty New York stories involving wallets and food choices, who is being picked on and who is attacking vary in the telling. Convenient facts get omitted from the narrative.

It’s best to start at $1.50 a slice.

That is what pizza was selling for about a year ago at a family business that is a combination vegetarian Indian restaurant, candy store and pizza parlor on Avenue of the Americas (also known as Sixth Avenue), between 37th and 38th Streets. It is called Bombay Fast Food/6 Ave. Pizza.
