The underground tour is more than a little crazy to see just how built up the city literally is. My favorite related topic were the spite mounds.

Flat bottom boats hold a lot of bulky cargo, but they're a nightmare when empty. So on the return trips they ballasted them... with fill dirt.

The tour guide makes the tour interesting. The actual sights are cool but you're effectively on a guided tour through maybe a few small blocks of buried sidewalk. It is not earth shattering stuff though the history is definitely cool.
In the end it was worth the ~$40, $20 for the tour I think, and I felt generous so I gave the guide a big tip since he was hilarious and took us on a slightly extended route according to some folks who had done the tour in the past.
I got the impression it wasn't much of an under belly, as it was a large part of the life around here.
