If you're looking for something neat to do while you're in Las Vegas, I highly recommend checking out the Mob museum. I was Very impressed! Make sure you give yourself a good 2 hours + to go through it all. This museum take place in a 3 story historical building in downtown Las Vegas. The museum is on all 3 floors. You start on the 3rd floor and work your way down. The second floor actually is one of the original Las Vegas court rooms. This particular room is where one of the high profile mob trials took place. The furniture and the wood work in the room was all original. Very impressive. As I ventured through the museum, I was continually amazed at how creative and artistically they designed each area and displayed the content. It was definitely top notch. I'm a huge Sopranos fan also so the entire museum especially appealed to me.
The staff was very friendly and professional.
Check this place out, you won't regret it!
