Piston Diner has been where it is for ages. You can see from some of the old reviews that this place used to be a rather leaky piston (engine analogy). New ownership, from what I can tell, has remade it greatly.
We were a party of ten, called ahead and were instantly told "yes, this is fine". When we got there, the tables were all set up in the side room for us. Excellent service. A couple of the meals arrived a little late, they ran out of Pepsi partway through, and they were out of their signature soup, but these were not unusual problems overall. Drinks were refilled quite well, good service. The main room includes the dessert tower and the salad bar, no foods on display in our little room, but the place feels surprisingly more like a diner inside than I thought from the outside.
Speaking of food... I would say "typical diner". There are some excellent offerings on the menu, but when they come out, you realize the ingredients and preparation are fairly plain. The Philly cheesesteak soup was interesting and I'm glad several of us tried that. The salad bar seems quite small, but you may load your plate with what they have there and I feel like I did fairly well with the limited selection. I was rather jealous of the seafood alfredo, and as I dug into the special Louisiana cajun pasta, I was struck by a few things:
* The raw peppers are kinda jarring. Should have been cooked (and probably red, not green, for flavor).
* The sauce has not a hint of Cajun in it. Nice and creamy, like an alfredo, but no spice.
* The chicken was fairly plain without the sauce.
But there was enough sauce. And just about everyone either finished their food or brought home what they couldn't finish. And they honored my coupon. So in the end, all the positives of this place bump it up in my opinion. It's not gourmet, but if you want to visit a Jersey diner or, as a regular, go for some diner food, Piston's worthy.
