If you've never heard of frozen hot chocolate at Serendipity 3 then you've obviously been hiding under a shell. Everyone talks about it and its exactly what it sounds like. Hot chocolate that's frozen and served with whipped cream on top. It might not be worth the $11, but then again you are in Vegas and nothing is cheap. Just relax and pay the price. It's worth it when you're craving something cold and sweet on a hot day. I've also tried the jalapeño bacon pretzel. It was huge, but it didn't taste that great. It felt like it was out for several hours so the texture wasn't that great.
