I went to Serendipity 3 to have a frozen hot chocolate.  I'd had one about 10 years ago in New York.  Honestly, I don't remember a thing about how it tasted but I figured it must have been good if there is now one in Vegas!\n\nThe place was crazy busy when we arrived but luckily I spotted a 'takeout' window on the side.  No biggie since I only wanted the frozen hot chocolate anyway.  Looking at the menu while waiting in line, I was shocked at the price for the frozen hot chocolate.  Most flavors were $11.  Flavors like 'peanut butter, mint or vanilla'.  No hint of fancy chocolate like Lindt or Ghirardelli flakes that might make the price worth it.  I bought anyway, the mochachino flavor, I wanted peanut butter but they were out and $12.97 later, ($1 for a plastic glass of tap water) I stood by the window and waited for my frozen hot chocolate.  They are fast, I will give them that, but what passed from the window into my hand was basically a grande frappucino at three times the price.  I'm not sure what others were raving about because nothing in that glass could come close to being worth the $11 price tag for the drink.  \n\nAs my friend and I wondered exactly why there are so many people at Serendipity we could only guess that 1 -they'd never been there before or 2- like me they couldn't remember having it the first time.  Apparently, if you actually sit down in the restaurant, the frozen hot chocolate is much larger which might have made me feel a tiny bit better.  However, either way, the melted milkshake with a load of whipped cream that is the frozen hot chocolate is not worth your time or money.  Go somewhere else.  There are plenty of gelato places in Vegas where you can get your ice cream fix if that is what you desire for 1/3 of the price.
