P.F. Changs is offering a complimentary order of Lettuce Wraps when you download the new PF Chang iPhone App and join the Warrior Rewards Program. I’m not sure if this freebie requires a purchase because I don’t have a iPhone to check it out. It appears to only be available on the iPhone right now :(. Click this PF Changs iPhone App link to get started. I’m a huge fan of the Lettuce Wraps at P.F. Changs!
