Pei Wei restaurants have a free frequent user card that you can sign up for. You present it, or just your phone number, every time you eat there, and after 10 entrees, you get one entree free. Most times, we find that our lunch order counts for at least 2, maybe 3 entrees, so you'll get to the free entree pretty quickly. Good food - a "cafe" subset of P.F. Chang's, I believe.
