I hate asian restaurants that mix up asian food from all different countries, then put it on one menu. It's never done really well because some dishes may be more on the authentic side, but others won't live up to standards.
This is exactly what you get at Noodles in the Bellagio - they mixed Cantonese, Mandarin, Japanese, Thai, Vietnamese, you name it. I guess they figured they need a place to serve all of the rich Asian guests, and this is what they came up with.
I had the wonton noodle soup, and it was SOOO bland.
Yuck.
