We stopped by Serendipity on a Sunday afternoon and took a seat at the outside bar. It was such a relaxing little spot and not too busy. I've been to Vegas several times but it was always really packed the previous times we tried to go so this was a very nice change. The bartenders were very friendly and helped us to decide the size of our treat. \n\nWe ended up getting a peanut butter frozen hot chocolate. It was delicious! It came out pretty quick and was just enough for 2 people - any bigger would have been overkill. I recommend getting the regular sized one and not the size built for 2...unless you really want A LOT of frozen hot chocolate. I would come back for sure.
