I got a single scoop of gelato (maybe mine was more of a sorbet) for $3.50 I think, which I feel like is unheard of in Vegas, especially at a fancy pants place like this. While I wasn't blown away by my choice of lemon, I can't complain about the price or amount of options JPP has, so that's why I'm giving a four.
I probably wouldn't get the lemon gelato (sorbet?) again because it was super intensely sour -- to the point where my jaws hurt a little bit every time I took a bite. I love sour stuff, but this was a little too intense. This is a very nice place to stop at when strolling around The Strip.
