Showing off Milwaukee

I know that asking for recommendations can be annoying here - but this request is a bit different from what I was able to find searching in r/Milwaukee.

I have a friend who wants me to help convince his partner to move here. What are your recommendations for the best of the best to show them as his first trip here?

Their main request is to see different neighborhoods and experience various parts of the city. I've got some ideas of my own, but I'm still learning Milwaukee since I've only lived here for a couple of years. I'd love to get ideas and recommendations from others with varying perspectives, so I figured this is the best place.

Basically, what is your favorite local thing that shows off our city that may be off the beaten path and normal recs everyone gives?
