One of the hidden places out in the Bellagio, unless you're a guest heading to the pool or the convention rooms you probably wouldn't wander towards this side of the hotel. Their gelato is really good here and it's supposedly the same gelato from the Jean Philippe Patisserie at least from what I was told.
I've also ordered their smoothies here as well, and they're pretty good but they're on the pricey side for sure.
There's iced water towards the wall on a counter near the right side of the cafe which is always refreshing.
