As I work very near West Coast I go there about once a week for a little treat or when I am craving decent western food. I have never experienced them being out of items although I stick mainly to the western food of chicken burgers, beef burgers and steak sandwiches... the last 2 I would highly recommend for some traditional good eatin!
I would eat there more often except the price in comparison to other options around the hi tech zone is a little expensive i.e. Other places 6 - 12 RMB, West Coast = 30 RMB for average dish listed above. Although the other places you can kind of feel your in prison with the way the food is shovelled onto your steel plate. With West Coast the service is always very good and your greeted with smile and a helping hand if you cannot speak chinese.
As suggested if your in the area definitely recommended.
