I absolutely loved learning about the history of Mobs, the culmination of Las Vegas casinos and the city's history, and the law enforcement resulting from the mobs destructive ways! Highly recommend this to everyone, I was fascinated by the whole experience!
Word of advice, allow yourself at least 3 hours to throughly go through the museum. It's dense with facts and they are all worth your time. I appreciate how they have preserved the postal office and courthouse and have made it into a museum! Also if you are a local Nevada resident you get a 50% discount on the ticket!
