The Pei Wei in Ballantyne is very consistent on quality and service. Changes to dish are easy and the wait time is within' acceptable limits. I sometimes go here for lunch and order either the Orange Peel or the Spicy Korean (creature of habit). They have one Coke (black) Freestyle machine, which means you may have to wait to get your drink (however, they do have Dr. Pepper!!!). The place will get packed during lunch time, so go early or later.
Be careful how you park in the parking lot, the spaces are narrow! If you go during lunch time, it is easier to park at the CVS/pharmacy.
