Noodle Asia had pretty fast service and decent food, though we found it slightly odd that my husband's noodle dish with seafood came out several minutes before the vegetable fried rice.
The location is either great or horrible, depending on his you look at it, since it's partially open to The Venetian's casino floor. So if you want a quick bite while still having a view to the action, it's great. If you wanted a quiet, more intimate meal, you really should go elsewhere.
