Charlotte Douglas International Airport is a complete madhouse, but the cuisine is off the chains.
I had a lay over here and was shocked at the sheer volume for a small market city. You would be forgiven if you mistook this airport for LAX or ORD, it is that busy. Huge lines and very few charging areas for your cell phone will frustrate even a seasoned traveler.
The food choices however are commendable. If you are hungry you owe it to yourself to seek out Carolina Pit Barbecue in the main terminal as it is the damn truth. Smoky, tender and so moist... truly delicious. A small piece of heaven in a travelers hell.
