What should a city in this world have?

Cities of Stone is playable, and it's early enough that what people ask for can still change it.

Each people builds its quarter in its own style, so a Dwarf street and an elven one look nothing alike. I'd like to know what you'd expect to find in a city here. A guild hall, a fighting pit, a harbour market, a wizard's tower that occasionally explodes.

What would you build first, and what's missing?
