I like Maggianos better than Carmine's.. I love the 4 cheese ravioli.
I go to the same Maggiano's that you went to, and it is really loud there.
Parking is always hard because there are so many restaurants, but if you go into the parking garage right above the restaurant it's sometimes easier to find a spot than getting one in the lot in front of Maggianos.
Next time tell your coworkers to go to Sanducci's on Kinderkamack Rd in River Edge.

Right down the street almost and great food! I think they have a lunch buffet now, too.
ETA: I've been 3 times, once for my HS reunion, and then the other 2 times we did family style, so skimpy portions were definitely not a problem, they keep bringing you as much as you want.
