I agree about Razza and Porta. Also, if you stay in JC for breakfast, you can walk right over to the City Diner. It's awesome -- not the typical diner at all. They have a great menu.
+1 on Hopsscotch. Great place to hang and watch the games with tons of hard to find craft beers. Definitely ask for Luke and tell him the Canes suck. He does have RU season tickets too.I highly recommend a place called HopsScotch. 286 Washington Street. It upscale craft beer/scotch place. It also has some great food. My friend owns the place. If you go, ask to see Luke and tell him The U will stink this year (he is a big Canes fan. ) Seriously, this is a great place.
Old school Italian , Laicos. Like being in an old mafia movie. Excellent food and fresh squeezed fruit juice for the cocktails (at least they used to do this).

Go to the melting point for brunch tomorrow. Great views of the city off th river in Hoboken
If you like diners and especially pancakes, give the Brownstone Diner and Pancake Factory a spin in JC - amazing pancakes of all kinds and great diner, too...
