Atlanta Hartsfield-Jackson International Airport again topped the list of being the world's busiest airport, catering to over 100 million passengers last 2016. Of course, being as busy as it is, it should be well-equipped with the usual demands of hungry and impatient passengers.

Before it became the airport giant, Hartsfield-Jackson used to have only shabby food courts for on-the-go passengers. Now, it became its own culinary hub for housing some awesome indoor restaurants. Are you one of its hungry passengers waiting for your next flight? Here are some of the best restaurants to eat in Hartsfield-Jackson:

One Flew South. You don't need to go in Michelin-starred restaurants and luxury hotels just to have a taste of world-class food. Hartsfield-Jackson International has One Flew South, and even though non-chain restaurants have been opening up left and right in the airport, it still remains one of the best. Their culinary offerings are so good, Thrillist reports that they have been nominated for a James Beard award.

Chicken + Beer. Fried chicken will always have a soft spot in anyone's heart, so much that even though this restaurant is way over in Concourse D, passengers do not mind going all the way while lugging their big bags. This restaurant's success is also partially because of being endorsed by rapper Ludacris, according to Travel Pulse, but mainly it's all about their two-piece chicken and chicken and waffles.

Grindhouse Killer Burgers. If you can't stand the long lines at Chik-fil-A, Grindhouse Killer Burgers is an excellent alternative dining spot. They're called Killer Burgers because their burgers are to die for, being made with fresh beef, turkey, and veggies stacked in fresh potato buns. You can also make your own combination or simply choose among their bestsellers. Vegan customers will enjoy their veggie patties too.

Jekyll Island Seafood Company. If you're craving for fresh seafood in between flights, then head over to Concourse F for comforting bites of Georgia coast specialties. Their seafood menu is impressive and surprisingly light, but it's enough to curb your growling stomach and sour mood while waiting for your delayed flight. Some of their best menu picks include the seafood gumbo, shrimp and grits, and fresh oysters.
