I always enjoy my visits to PF Changs.  The quality of the food is consistently good and flavorful, and the atmosphere and decor of the restaurant is very tasteful.  Every time I come in you can see guests laughing and smiling so you know the enjoyability of the restaurant is contagious.  The staff is always very pleasant and accomodating and informative if you have any questions.  A bonus is that they issue out a 10% off discount card that I received after a visit in downtown San Jose, CA.  How can it get any better?
