I lived in Philly for seven years, and thought I'd never find a hole-in-the-wall East Coast pizzeria in Tempe, but here it is!
When it comes to pizza, I'm a sauce man, and there's is really really good (crust is great as well, but I'm less fussy about that). They've got great selections, all pretty reasonably priced unless you go nuts with additional toppings rather than opting for one of the pre-defined combos.
My real find was their non-pizza Italian entrees. Like any good East Coast pizza shop, you can also order pasta, meatballs, etc. Their lasagna is off the hook and the portion is ridiculously large. They also offer a "side" of meatballs for $2. This side is two jumbo meatballs, served in its own big container with marinara and cheese - a meal in itself! And their side salad for $2 is also really tasty. I order lasagna with two sides of meatballs and a side salad for $12 then live off of it for an entire day. (Note to Tessio's - your ravioli is so good too, but a little skimpy compared to the lasagna).
You want real pizza or pasta delivered in Tempe, this is your place.
