We (my wife and I) usually get one of each antipasti and share, but you can ask for more. I have dietary issues with certain seafood so I sometimes just ask for a plate of the mussels and they've accommodated. I usually get the traditional Bennie. All of the soups are good, but I think celery is worth trying because it sounds really weird, but it's good. I skip the waffle/pancake because they are good but I'm saving room for other stuff. Order the off-menu grape and gorgonzola pizza or skip it unless you have a party of 4+ and then just get one pizza to share (again, gotta save room). Entrees, the veal is good if you're into that, chicken parm was really good, but the lasagna is the standout.
I've never been disappointed with anything I've eaten at Palo, so don't stress over it too much.
