Is there a good place inside that has Chicago Dogs? And is there a good Chicago Pizza place inside?

There are several spots you can go to within the airport but don't expect anything amazing within the airport.

Yes there some decent spots that you can try out but they are in different terminals. For example: 🌭 America's Dog which is Terminal 1 Concourse C Gate 18 Chicago Style Hot Dogs: Terminal 1 Concourse B Gate B14 & Concourse C Gate C8 Terminal 2 Concourse E Gate E3 Gold Coast Dogs: Terminal 3 Concourse L Gate L4 For Pizza 🍕 there is Reggios Pizza in: Terminal 1 Concourse C Gate C18 Terminal 3 Concourse G Gate G8 & SAME terminal Concourse K Gate K4, It is good here but it is pricey compared to outside of airport 🛫
