Yeah. All Chickfila's are closed on Sunday. That's interesting that the ones in your area are lds owned. In this area all the Mennonite owned stores/restaurants are closed on Sundays(and there are a lot of em). So, it's not so unusual to see that here.(Still, I can't seem to remember that when I get a jones for some chicken strips on a Sunday!) Actually, the Chickfila that I frequent is a free standing one. From my understanding, that is unusual. That most of the Chickfila's are in malls.
I found this info on Chickfila's website:
Q: Why is Chick-fil-A closed on Sunday?
A: Our founder, Truett Cathy, made the decision to close on Sundays in 1946 when he opened his first restaurant in Hapeville, Georgia. He has often shared that his decision was as much practical as spiritual. He believes that all franchised Chick-fil-A Operators and Restaurant employees should have an oppurtunity to rest, spend time with family and friends, and worship if they choose to do so. That's why all Chick-fil-A Restaurants are closed on Sundays. It's part of our recipe for success.
