Where South Plainfield Gathers
The Park Ave Diner has been the neighborhood's around-the-clock kitchen — good food and a familiar booth always waiting, no matter the hour.
What our guests are saying
I love fresh-squeezed orange juice. Next time I will ask for a mimosa with my omelette.
Ivan D.
This is an amazing place. My uncle recommended this spot to me and my wife, and we enjoyed everything about it. Can’t say that about many diners.
Tony D.
Good place to grab a meal. Had the same waitress twice but never got her name. She was the best for sure. The fam meets once a month to get together and never disappoints.
Chris T.
Always enjoy ordering breakfast from here. The service is great, the food is quick, and I enjoy coming here often.
