I went to Muscatine, Iowa on a work trip once. There was a restaurant there called Button Factory. It was housed in a former button factory. Pretty old building. The bar top had an epoxy inlay with embedded buttons that were produced in the factory.
The meal was pretty good. The restaurant closed in 2012.
There was a button museum at the time, though I never made it in. I'm not sure if the museum is in the same spot as the restaurant was, as I was there in 2017.
One block over from the museum, there was recently a partial building collapse. 20 buildings were evacuated and 17 are still not able to be occupied.
