First, I got lost.

I was trying to find GA Chapter Room , the speakeasy-like restaurant located under Taco Mac at The Prado in Sandy Springs. But GA Chapter Room is not just a basement; it's a full-fledged public restaurant (until recently, it was members only) serving a smattering of shared plates and main courses. Once I stumbled upon it, I realized how much of a treasure the restaurant—and its menu—is.

Second, I had to press a button to get inside. Once the hostess opened the door, I walked into a large, dimly lit room with dark brown velvet curtains separating tables for, you know, privacy. I sat down, ordered and received a plate that runneth over with Springer Mountain fried chicken breast resting on a soft Holeman & Finch brioche bun. There was also a side of truffle fries and coleslaw. But back to the main event—the chicken sandwich. I took a bite. It was fried to perfection and flavorful, surprisingly reminiscent of mustard. When I checked between the buns, there was no mustard. I continued to eat the chicken sandwich, and with each savory bite, guessed at the seasonings and wondered if someone’s Southern grandmother was in the kitchen frying up batches.

Eventually, I asked Adam, the beverage director, who was at Chapter Room that night, about the seasonings.

“It’s a secret,” he said.

Later, he came over and whispered, “The mustard flavor is from a sprinkle of dry mustard seed spice.”

That’s what gives the Gold N’ Crisp fried chicken sandwich so much flavor—the mustard seed spice, which heats and highlights the other ingredients.

While it’s no secret that there’s an abundance of good food throughout metro Atlanta, GA Chapter Room tops the list when it comes to a finger-licking good chicken sandwich. And, the entire plate is only $9. Privacy included.
