I'm a big fan of Buddy and the big show cake boss. When I was visiting and found out he had a bakery in Vegas I had to stop by!!! It was extremely busy so I suggest you arrive a littler earlier then opening time. The line was out the shop and it isn't as spacious either.
Desserts are are a little over priced for something you can make at home. The cannolis are very yummy, some of the cupcakes and mini cakes I bought were a little too dry for my taste. It was still cool to check out though, and be able to see some of the staff working and making giant creative cakes for special events.
