We were getting tired of the Rt 22 diner and IHOP was full so we tried the Union Plaza Diner since we have never been there before. I was shocked! The ambiance was warm and comfortable; Leslie, our waitress, was pleasant and patient, even when my girlfriend had difficulty making a selection. The food was both fantastic and the portions...

Menu hasn't changed in years...I find it is not clean...floor tables etc. I occasionally try it to see if it's changed but it's been downhill for over 2 years now and I'm sorry to say so since there was a time I'd even eaten there for breakfast and dinner in the same day.

Nothing special but not bad. Staff were polite and friendly. Service was quick. Food was what one expects of a Jersey Diner. A lot of comfort food.

Stopped here on our way back from NY. Not impressed. They seated us by the ONE bathroom in the entire restaurant so that was enough to gross me out. I ended up having to take my 7 year old in, and it definitely needed some attention. Ordered a burger, lamb gyro...everything lacked flavor! Asked for juice, they served it warm.... More

We used to love this diner. The service was great and the food even better. It was sold a few years ago and since then the service has declined considerably and unfortunately so has the food. This may seem petty but they've replaced their Heinz ketchup with a brand called I Taste Great. Well.....it absolutely does NOT taste great. It's... More

Stopped by for an unplanned breakfast. Difficult to drive into parking lot. Small entrance off a busy Route 22. Blocked by a deliver truck. Immediately was turned-off. Tremendous safety hazard. Not many patrons at 9 A.M. Service not forthcoming. Wife's breakfast not good. Mine was OK.

Something happened to the U.P.D. a while back; new owners or something. The food quality fell off. We had been big fans for more than two decades, but we began going to other diners. We recently returned and found that the quality we remembered had returned. We've gone back several times since and things are still terrific. We're so glad... More
