We had a short stack with eggs, bacon and juice, added potatoes. Also, had corn beef hash! Great breakfast. Very friendly quick service. When in NJ will go back to the Union Plaza Diner!

My whole family loves the Union Plaza Diner. The food is absolutely delicious! The shrimp kabobs are so so good, and so is the Cobb salad. My husband loves the gyros and my little grandson loves th grilled cheese kids meal. He loves that he gets ice cream with his meal. They also have the greatest cheese cake ever, even... More

Used to be very good but it went downhill. Pastry is always stale, food is bland and the place is dirty.

Came in for burgers ended up with tacos and shrimp scampi. I had an awesome meal with my daughter. Richard was an excellent waiter too. Thank you, you never disappoint for the 15 years that I have been coming here.

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
