I got a burger there and as soon as I ate it I felt ill, went back to my hotel room and threw up about two hours later.  Had diarrhea for the next 3 days.  I hadn't eaten anything for about seven hours before that, so pretty sure that's the only place I could have gotten food poisoning from.  Ruined my trip to Vegas pretty much.  I emailed the restaurant and Mandalay bay about it, never got a reply.  Never going back there again.
