Mob Museum: Downtown Las Vegas 

What does Valentine's Day 2012 and the famous St. Valentine's Day Massacre have in common? Both are related to the mob!
The new Mob Museum is located in the former post office then the federal courthouse where the Kefauver hearings on organized crime were held in 1950-51.
When you're ready to give the slots and tables a rest, the Mob Museum is just two blocks from Downtown Las Vegas' Fremont Street Experience at 300 Stewart Ave.
