Actually between 2 and 3 stars...
Marginally better than the Thai-Asian restaurant at Bellagio... but not by much... (although it is a more attractive looking place than Noodles). Ingredients are fresh and the service is adequate... it's just that the food is okay... nothing at all special.
Prices are typical for this category 'Strip' restaurant... not worth it... but no surprise.
A good number of folks visit, as it's one of the limited number of restaurants that are part of a comp package at Aria.
