Found out about this in a UK paper detailing old stations in USA worth a visit and as I love Art Deco I dragged my husband to cincinatti (road trip Philly to Chicago)
Definitely worth visit, we did the History museum only as had no children with us and found it v interesting. Especially loved the models of Cincinatti in 1st area. Docents were very helpful and knowledgable.
My only criticisms: would be nice if museum had come more up to present day and if you could have had some sort of handout describing the entrance hall etc. However, there are tours at weekends, we were there Monday!
