On our way out of Vegas, we stopped by Serendipity for a Frozen Hot Chocolate, which we'd had a couple years back. It was indeed a warm Friday afternoon so a nice cold drink would be a welcome treat, which it was; delicious even. That's what the 2 stars are for. Everything else about this place was no good. At 11 bucks for a cup of cold cocoa with whipped cream on top, you'd think they'd at least remember to actually GIVE you your drink. Others in our party were called up to pick up their drinks. We waited another five minutes and finally went to the window to ask. They'd forgotten to make it.  FAIL. Also, they charge a whole dollar for tap water. Seriously, we were paying customers, give us the darn tap water! Tasty, yes. Overhyped? You betcha.
