Love this place - great burgers - best of any airport I have been to. When in Charlotte Airport, which I am in a bunch becasue I fly US Air, this is my go to spot.
You will notice this restaurant in the wing becasue it is almost always busy. Expect to wait or cozy up really close to someone at the bar. The interior is whimsiaclly decorated with old comic books, posters and ample TV's. For those on the run, they have a quick service counter to the left of the opening. Music is not overpowering.
The menu is all burger bar with very few salads. For those that don't eat cow there are other options like turkey burgers and chicken burgers. Their are a number of composed burgers with ingredients based on theme. For those that like to build there burger there are a plethora of options from white cheddar to applewood bacon to fried eggs.
I have never had a bad meal here even if I was eating a turkey burger. You can even eat paleo here becasue of all the options. I will say the only dissapointment are the fries. That not withstanding, it is always a safe and quite tqasty bet in the airport.
Until by next flying gastronomic escapade, dine fine.
