Insisted on visiting this Serendipity since I had such a good experience at the original location in New York. I was severely disappointed in my experience.
First, the atmosphere is not the same, although there is still that whimsical feel it just felt off for some reason.
Secondly, the frrrozen hot chocolate here is a poor, poor copy of the one you would get in New York. We got the mint frrozen hot chocolate for 2 and the size, although still big, seemed much smaller than the portion at Serendipity NY. But my biggest gripe is that it was lacking the fine ice crystals that I feel make frrrozen hot chocolate so unique. The drink wasn't nearly as cold as it should have been and since it lacked any ice it felt more like a melting chocolate milkshake and felt very rich and heavy as opposed to rich yet still refreshing.
The menu is also limited so there are some items missing such as the frrozen pink lemonade which is delicious and would be perfect in the Las Vegas heat. If you love Serendipity and find yourself unable to make a visit anytime soon to New York, Serendipity 3 might be a good option but if you've been to the others and are looking for the same experience I think you'll end up disappointed.
