Purgatory Pizza (3415 N. Clark) is offering pizza in exchange for your soul. Sign it away (no free pizza without a signed contract) and get a slice of cheese, pepperoni, or sausage pizza on a thin crust that's made with PBR instead of water. The offer's good through November 1. On November 2, All Souls' Day, you can get your contract back (and your soul, if it'll have you) if you come in and buy a pie, which explains the shop's slogan: "If you don't like our pizza, go to hell." Call 773-975-6677 for more info.
