On July 11 only from opening until 7 pm local time at participating Chick-fil-A restaurants, receive an entree for free when you dress up as a cow (or wear something cow-related) during its Cow Appreciation Day. (Kids who dress up receive a free kids' meal.) That's the best such deal we've seen from Chick-fil-A this year. This promotion is valid for breakfast, lunch, or dinner.
