I'm giving Pei Wei four stars because if I really wanted authentic Asian, then I'd go somewhere else for authentic Asian. Pei Wei isn't bad at all, especially if you know exactly what you want when you walk in and you know what you're getting for the money. It's a "slightly slower fast food" joint (I don't put Pei Wei in the same category as McDonald's or BK, because it's not) and I have to throw Pei Wei a bone because they do offer plenty of vegetarian and gluten-free options.
Pei Wei is a go-to when I want carry-out and I want it simple and clean and I don't have to think too much about what I want. I know it won't disappoint and I'll usually have leftovers for the next day (you shouldn't leave Pei Wei hungry, as the servings are only slightly smaller than a bass boat).
I'm not one to do Pei Wei every week, however it's not bad at all when I don't feel like cooking and just want to stay in with some good carry-out.
