I used my credit card at this lounge last Monday watching MNF, it was the only place in Vegas I used that card. It was cloned by some staff member and used to purchase crap a nearby supermarkets. I sat at the bar and ordered from the bartenders. Definitely something going on there. Based on my conversation with Citibank, the card was cloned since it was present and swiped at other places the following morning or late that night, despite me getting the card back.
Otherwise the place is nice, I'd give it a 4/5 since it's got a nice feel and they do a good job with MNF. However, having your credit card stolen by staff and spending hours to deal with cleaning that up leave me no choice but to give it a 1-star rating.
