Unfortunately we found this museum really boring. Neither of us are really interested in the mob/mafia, so that might be why. It seemed like they had a lot of artefacts that weren't really important (like Dick Tracy comic books and a plastic spoon from an underground casino). There was also a LOT of reading and not a lot of interactivity or interesting artefacts. I'm giving it two stars because the staff were all very friendly and the gift shop was cool.
