As the discount little brother of PF Changs I think they do a pretty good job on getting a few meal choices out to the table hot in a timely manner.
Although since the expansion of their menu and addition of about 15 new items I feel quality has suffered.
(The Thai cream coconut sauce is like cream O mushroom soup from a can)
But as stated above the expectation should be of that inline with Panda Express as the price range is fairly close to that mark.
The higher percentage of their rice and noodle bowls are a good value and are served hot and fast. They have some kids items now as well.
Its decent Asian "fast" cuisine and they do have some healthy options which rewards them an additional star.
Just set your expectations accordingly and PW will be a good lunch dining experience.
