From the infamous Chicken Quesadilla to the out-of-this-world creation known as the Double Double Down, scroll down for a few favorites savvy fans have stumbled upon over the years:

Double Decker Sandwich

Get two patties instead of one when you order any sandwich on the menu "double decker."

Chicken Quesadilla

Most Chick fil-A locations carry tortillas; so ask your local one if they'd be willing to whip you up one of these off-menu favorites.

Root Beer Float

Simply request a scoop of soft serve in your root beer and poof!

Chicken Bacon Ranch Deluxe

Ask about decking out your Deluxe Sandwich with bacon and ranch dressing.

Buffalo Chicken Sandwich

Turn up the heat on your spicy chicken sandwich by asking for buffalo sauce on it.

Lettuce-Wrapped Sandwiches

Your waistline will appreciate this diet-friendly option. Ask your server to swap buns with lettuce to create this low-carb meal.

Grilled Cheese

Vegetarians love this one. Simply inquire about adding cheese to a toasted bun.

Double Double Down

This bun-less sandwich isn't for the faint of heart. This monster features two slices of fried chicken between two more fried chicken patties layered with cheese and bacon between each slice. Order at your own risk.
