Today, America has around 3,000 diners. In New Jersey around 570 diners operate, more than any other state. About half of all the towns in New Jersey, 284, have at least one diner.

Only three major companies from the 1920s and 1930s still build diners: Kullman, Paramount Diners, and DeRaffle Manufacturing Company. DeRaffle is the only one not located in New Jersey; it's based out of Rochelle, New York.

Route 130, which runs from Carney's Point northeast to New Brunswick, has more diners on it than any other road. It has almost two-dozen diners.

Even after the commercials set in Rosie's Diner ended, New Jersey diners can still be seen on television and in movies. Scenes from the movie "Boys on the Side" were filmed in the Bendix Diner in Hasbrouck Heights. On TV, a series of Tums commercials were filmed in the Harris Diner in East Orange. Diners even turn up in music. New Jersey native Jon Bon Jovi put the Roadside Diner in Wall on the cover of one of his albums.
