HEY!! Guess what?? I forgot to say that last night when we were driving on the Strip, we saw that they are opening a Serendipity 3 at Caesars Palace!
It's not actually in Caesars, but on the property in a separate building. They have one in New York City and I first heard about it on Oprah when she was raving about their Frozen Hot Chocolate dessert.
I think it's set to open sometime in April, so we can all go there in June!! Probably on the day we hit the Forum shops since it's right there.

(we can eat there for lunch instead of the Cheesecake Factory if y'all want)
Here is a link to their website for the NY restaurant:
