PDQ out Chick-Fil-As Chick-Fil-A.
Customer service is an art, and these guys nail it. From the unused umbrellas at the doors (although if it raining I have seen them escort diners to their car), to the prompt and polite interactions with the staff PDQ is firing on all cylinders.
Once my order, which was ready before I finished my transaction, was wrong and PDQ fixed it in seconds without question, and even offered up double apples when I declined the toffee dip due to allergies (I guess not too many people order apple slices with kids meals).
So if you are in the NW, and are craving good food and good service, stop off at PDQ and eat lunch with these guys.
