Not to be confused with the Patisserie at the Bellagio -- this one is at the Aria!
I ordered a soy chai tea latte here along with a rose raspberry macaron after a much-longer-than-I-remembered trek from the Marriott Grand Chateau. Stupid me forgot to ask for my chai to be iced, but it was still pretty decent. Tasted like your general, run-of-the-mill chai tea latte (if you like yours a tad more sweet than chai-y).
The macaron was pretty good, too, once we finally got back to the hotel room with it. The raspberries were fairly fresh (like from that morning). It was overall chewy and fairly flavorful, but we had no idea what the filling in the middle was made of.
