Wendy's
Wendy's isn't exactly known for homestyle cooking, but it's pretty good fast food with a family backstory. Most people know the restaurant chain was named after the founder's granddaughter, Wendy, but did you know that the word "mom" is secretly written in Wendy's shirt collar? This was something thrown in to commemorate the founder's mother.
Chick-Fil-A
This one isn't exactly a secret, but it's definitely one of the most adorable logo designs on the list. Chick-Fil-A wanted to incorporate their signature chicken into every part of their branding, even the title. So, they put a chicken design in the letter "C" on all their signs. The smiling poultry face is now a fan-favorite. Now that's cute chicken!
