There is also a word Diner, are you sure you aren't getting it confused?

If you're living in a southern country {Virginia, Texas, Alabama,etc.} then you may hear people pronounce "dinner" as "die-ner" because of their southern accents.

hello, Alex from New Jersey

Sorry, I meant to say I am from the great and wonderful state of New Jersey.

I am from New Jersey, I think the state with the most diners in the US. They sometimes have lots of chrome, marble, and mirrors, and are commonly run by Turks or Greeks. There's the Diamond diner, the Empire diner, Six Brother's diner. I guess you probably read about diners on the internet.
