I make it an objective to visit Serendipity when I'm in vegas.. for the Frrrrozen hot chocolate and the nachos. That's what I order, every single time I come to vegas and I'm probably going to continue to do that =)\n\nThe wait is always super long though, that's the only down side. But, if you're only looking to get the frozen hot chocolate or anything else, they have a to-go window on the side!
