Why 5 stars?
Because you have to pick which things you want to see in Vegas and if you're in the area, this is worth it.
You will
(A) See the world's largest chocolate fountain
(B) See a huge selection of beautiful hand crafted desserts that are actually reasonably priced for the Bellagio (many around $7)
(C) Grab a bite if you're looking for ice cream, coffee, or a variety of crepes that looked unique and delicious
Walk through the Bellagio on the left side to find it...just pass the big art garden thing.
