This review is actually for the Cedar Park location, which is open but does not appear in CitySearch as of yet.
My wife and I have eaten at the Cedar Park location of Rosie's on 3 different occasions and each time it has been the same. While the food quality is good, the wait time, even for simple dishes, is excessive. Ordering the same or similar dishes at other noodle shops (like Tan My on Ohlen Road) is easily less than half the time of Rosie's. From our home in Williamson County, we can drive to one of the other noodle shops in a more central Austin location, place our order, and have our food in front of us in less time than it takes to get our food at the Rosie's Cedar Park location, which is only 5 minutes or so away from us.
The girl who takes the order at the Cedar Park location isn't very friendly either, she could really use some work on her customer relations skills. I get the feeling sometimes that she considers customers to be somewhat of a pain to deal with.
As I said, the food is good, but the poor service quality and excessive wait time will prevent us from making any return visits for a while, if at all. I'll monitor this site for improvements in the situation, but if I don't see any, then no biggie - there are plenty of good noodle shops in the Austin area with quicker, friendlier service.
Pros: Food is Good
Cons: Slow, mediocre to bad service
