No! NY and northern NJ pizza is still 15 to 18 inches in diameter. Pizza hut and other chains don't have them that way, but NY pizzeria do.. I don't know about Trenton, but i expect they still have this style. you can even get them that way in southern NJ, just out side of Philly.

One pizza is cut into 6 or 8 slices, and sold by the slice Two slices is a lunch special--$3. near where i work (right next to NY city call and civic center)

I still remember my first slice too, in the Arther Avenue section of the bronx, 15 cents bought a slice and a 8 oz fountain soda. It was heaven! the best part, was it was a meat free food! it very quickly became our favorite food on "fast days"--when we couldn't eat meat.
