Photo Gallery | Customers show their support on "Chick-fil-A Appreciation Day"

Today was unofficial "Chick-fil-A Day" and customers showed up in droves to eat their favorite chicken meals and show their support for the restaurant.

The appreciation day was organized by former Arkansas Governor Mike Huckabee on Facebook. The day is in response to criticism of the restaurant's president, Dan Cathy, for his comments in a Baptist Press article that his family and Chick-fil-a supports "the biblical definition of the family unit."

Nearly 640,000 Facebook users RSVP'd to the event. In response, Chick-fil-A opponents have planned a Kiss Mor Chiks event for Friday, August 3. They encourage people of the same sex to go to their local Chick-fil-A restaurant and kiss each other.
