OK, I be honest: I'm not a big fan of the Hard Rock in LV. But when I was there two month ago, they beat everything:

I asked the gift shop employee, if they have used dice and she told me, yes, they are over there. What I found there was a bowl full of souvenier dice and I told her, that I'm looking for the dice from the tables. Then she answered: "Ohh those ... we're out of them right now ... but the dice in the bowl are used too ... all our dice come from the tables"

Never heard a gift shop employee lying at me with such a beautiful smile on her lips :-)
