This is the best gelato in Vegas, hands down! I used to go elsewhere for gelato/ice cream in Vegas, but once having tried Jean Phillipe's, I keep coming back.
I like the Aria location because it's in an open space with more variety and choices of desserts. It's easily accessible from Vdara (if staying there). It's also less crowded than the Bellagio location, so it's much easier to ask for samples here before choosing flavors! I say flavors because one is not enough! I've had the pistachio and coconut. Soft, cold, and rich in flavor! No icy ice cream and no dripping all over (unless you eat it outside in the summer heat). There are friendly employees and a beautiful display of desserts.
