If you're an adult and dress in any sort of cow attire on the day and walk into any Chick-fil-A restaurants, you can get a free entree. Children in cow costume can get a free Kid's Meal.
The freebie is good at Chick-fil-A restaurants nationwide and is available from opening until 7 PM (local time) on July 10, 2018.
