Went here with my husband 2 weeks ago on a Friday afternoon, & W-O-W! There are not enough good words to describe this place, it's definitely a hidden gem in the downtown area! 3 floors of mob history with plenty of visual effects to keep you intrigued. The staff is excellent, the museum is very well done, & there's a gift shop with some pretty groovy souvenirs ( that are also reasonably priced) on the 1st floor before you exit. All the proceeds from the gift shop go towards funding the museum, & you get discounted admission if you're a Las Vegas local. If you're into mob history/mob movies, & are looking for something awesome to do in Las Vegas, set aside a few hours & give this place a visit!
