For a 6-year-old boy in Texas, Chick-fil-A fries are one of his favorite things to eat, for a very special reason.

Christopher Cataldo suffers from a rare condition, Eosinophilic esophagitis, also known as EoE, that makes most foods off limits, because they trigger a severe allergic reaction. Kellie Cataldo, the boy's mother, said on Facebook that doctors allowed the boy to eat only seven foods: Apples, grapes, plain rice, potatoes, tomatoes, lemons and bananas. Christopher also suffers from seizures, Addison's disease and a weakened immune system, meaning he has to limit his exposure to crowds of people.

Cataldo enjoys fries from Chick-fil-A, which were approved by his doctors, according to KHOU. But because of Christopher's immune system issues, the Cataldos visit the drive-thru instead of going inside the restaurant.

When Chick-fil-A franchise owner Brad Munson learned of Christopher's condition, he decided to make the boy an honorary owner for the day before the newest location in Tomball opened Thursday, KHOU reported.

Christopher was able to check out the playground area, cook up his own fries and work the drive-thru as part of his honorary owner duties. He hopes to one day be able to open his own Chick-fil-A location.
