Is pei wei asian diner a healthy place to eat?

my gf tends to eat alot of pei wei, like every other day just because she feels like it. im kinda a health freak and dont think its healthy but i went on peiwei.com and looked at the nutrition info and it looked perfectly fine to me...wasnt high in calories, fat and has fiber and protein. i was wondering if its okay for her to eat out that much? i personally dont think it is but i have no reasoning behind why i think that.
