Union Plaza Diner

Food & service are great. 1 tip, don't sit behind the bar if you do not wish to listen to the employees crying about scheduling, staff & customers. It seems that the bar is a break room/office. Enjoy

Also, watch with the cleaning staff , they will sweep while you eat. Not considering the chance of dust getting on your food, might be ok for some but it is a seasoning I can do without. Thanks!

The breakfast combos are pretty huge in serving sizes. It's great if you have a big appetite or want to split the dish with someone.

Lots of Spanish themed food...good for after church ! A nice alternative to Tops Diner if you're up for the drive.

It's a typical diner menu. Everything I've ever ordered here was good though. I do love their pancakes , light and fluffy!

Everything that I've ordered here (alcoholic drinks included) has been really good! I've always had good service as well .

Great food, best diner I've ever been to (although I may be biased since I lived most of my life a few miles away).

The homemade desserts are always delish. There isn't too much I don't love about UPD. Go late after midnight and watch the drunkies pile in!

The place over all, food and trained service is great! Enjoy ♡♤

Disco fries and omelettes ..best diner in union county

Great diner with one of the most extensive menus. The portions are huge

The food has always been good. Good service and desserts are really very good.

The menu is as thick as the bible. If you know what you like, just order it and assume they have it.

Just about everything is good. I loved the chicken fajita omelette

Emily is the best waitress EVER!! Smiles all through and just has the best personality...

Try the buttermilk pancakes with walnuts , strawberries , and bananas , with a scoop of ice cream .

They make good sliders here, and good shrimp cocktail :)

Nice place, coffee was really good and great menu

The menu has chapters! If you don't see what you want to eat... It hasn't been invented! Yum

The best New Jersey diner there is!

Great service no matter what time it is! French martini 's are awesome here : )

My experience on 6/6/17 was bad. My waitress was excellent, the meatloaf was adequate, but the reception was horrible. New owners who do not say thank you or was everything all right. Never again

The menu has more pages than some novels .
