Because the proposition of free Mongolian beef is hard to ignore, P.F. Chang's is currently offering a free entree coupon.
The casual pan-Asian restaurant chain will send you the coupon by email. The catch is you'll have to sign up for promotional emails from P.F. Chang's.
To get your coupon, you'll have to head to its website here and fill in your name, email address and zip code.
The coupon is for dine-in only and it's good for up to 14 days from the date that you sign up.
The coupon is also valid with the purchase of an entree, so bring a friend.
