I know you're heading West on 80, otherwise you would be taking 287 to the Thruway...
Someone already mentioned the Garden State Plaza and a chain resto, but in the same mall is Napa Valley Grille, an excellent and reasonable lunch menu.
Oceano's is just off 4 west, 1/4 mile from 17. Very good.
It needs a U Turn on 17, But Bistro 55 is a good choice as well.
Further north, there's a good pub-style lunch at Brady's at the Station, Ramsey. Just a 1/2 mile off the Lake St exit.

Assuming you are coming from Western New Jersey.....The Royal Warsaw in Elmwood Park, on River Road is just a minute off Route 80.....easy off and back onto Route 80
If you are in the mood for pizza, both Lodi Pizza and Pizzatown are easy detours on Route 46.
