How big are the slices near you? Im assuming large-ish like a NYC slice, where 6 slices will make the pie. If you are paying $5.00 for a slice of cheese pizza in Phoenix, that means a whole cheese pizza would cost $30 USD? That is insanity. Granted I think it would be cheaper if you bought a whole pie, but for dough, cheese and sauce that is still a very healthy profit.

I agree every region has its own good cheap food. Interesting stuff.
