Wawa has generally good hoagies (they’re a Philly-centered chain, so I’ll use their vernacular), and above-average coffee. Their hot food is usually pretty disappointing, because they put all of it through convection ovens (vs frying/grilling/deep frying/baking as is usual).
They recently rolled out pizza in my area (northern NJ), and while I haven’t personally tried it, friends say it doesn’t hold up to what local pizza places can do, but it’s better than big chain pizza.
