Yup, Vegas finally has a serious history museum downtown. The Tropicana's Mob Attraction is entertainment, but this downtown heavyweight is all about the real story of both gangsters and the Feds who tracked 'em down. It's inside the historic courthouse building where the Kefauver hearings happened back in the day. Parking costs $3, or park in a casino lot or garage instead and just walk over to the museum. It's two blocks north of the Fremont Street Experience.
