7 cult-favorite Chick-fil-A menu items that you can only get at certain locations

More than 190 locations in the Northeast and Midwest serve a special cheese sauce that can't be found at most Southern locations.

In Southern California, a number of Chick-fil-A locations serve guacamole.

Some locations in Texas and New Mexico have jalapeño peppers on the menu.

As of August 2018, nine Chick-fil-A locations in Iowa, Arizona, and Arkansas serve chicken gravy.

Chick-fil-A first started testing mac and cheese in July 2017. The dish is available in certain locations in Texas, Maryland, Tennessee, and Georgia, the Daily Meal reported in 2018.

The fast-food chain experimented with a number of different mac and cheese recipes — including one that featured cauliflower — before settling on this one, Business Insider's Hayley Peterson reported.

Mac and cheese isn't the only regional Chick-fil-A test. In January, the chain began testing the Spicy Chicken Strip Biscuit in Yuma, Phoenix, and Tucson, Arizona.

In January, Chick-fil-A began testing brownies at locations in the Bay Area, South Florida, and around Richmond, Virginia, for a limited time.
