CHICAGO || pizza
633 North Wells
2801 North Lincoln
A really good stuffed pizza, but not worth the ridiculous wait usually required for dinner at the Wells Street location. The lunch special is a much better option, with a personal stuffed pizza, soup or salad, and soft drink for about five and a half bucks. The Lincoln and Racine restaurant is bit light on amenities, existing as more for carry-out and delivery, with a couple of tables.

Boasting "all natural ingredients," Edwardo's has a good crust, and the spinach stuffed pizza is damned tasty.
3006 North Sheffield
The key here is that Chicago's Pizza is centrally located, is open until 5AM, and has slices of stuffed pizza for $3.00 each. I don't think I've ever suffered from a hangover if I stop there on my way home. The pizza is pretty good when you're sober, too.
