I know this post is incredibly American-centric, but it might help you find analogues more common in your city:
What I want you to think about, as much as landmark types, is what kind of places are people already gathering at en masse? It’s midday on a Saturday, or a Friday evening, where are people spending their time socializing? You’ve got a friend coming in from a few hours away, where do you take them to show off the cool parts of your city?
EDIT: One other suggestion I might make, if you haven’t already, is to set your bonus location to a city in another country, so you can see what types of places are being nominated in Chicago or in London or in Australia, and use those to help inform ideas in Az-Zāwiyah.
