Saw both locations of this. I have to say that the Chocolate Fountain in the one in the Bellagio is awesome. Who doesn't want to just stick their head in there? I only tried one thing from the location in the Aria and that was a Pain au Chocolate. It wasn't too bad. It was extremely crispy on the outside, like the kind that is so brittle that big pieces sort of shatter off, not the nice, light flaking you get with others. However, it was nice and buttery and had plenty of chocolate in it. I was pleasantly surprised. I am usually disappointed by most croissants, but this was pretty good.
