Combo meals include an entree, side item, and fountain drink.
To help customers along, Chick-fil-A has a "cow starter kit" available on their website that features printable pieces for a cow costume.
For those not yet ready to go full-on cow, you can still get a free entree of your choice by wearing any cow-spotted accessory, like a hat, shirt, or bandanna.
If you're wondering "why cows?" The reason is that Chick-fil-A has long used (running on 18 years) cows that implore/cajole audiences to "Eat Mor Chikin" as part of the chain's marketing efforts.
