I have found that most restaurants in my area do deliver but they severely restrict as to how far they will go, so I am mostly out of luck. I think that the answer to your question is mostly a cultural one, pizza places are expected to deliver and be open 24 hours because, hey, it's pizza. However, there is not so much pressure on other restaurants so they avoid the logistics of providing the service or they do so but don't go very far away.
