Do city center and city's center mean the same thing?

I don't think so. In "city center", "city" is a noun used as an adjective. In "city's center", "city" is a possessive noun.

I'd have to think hard in order to consider a real discernable difference beyond that of a nuance between the two phrases.

Maybe someone else can talk about some sort of difference between the two.
