There's nothing I like more at an airport than finding an eatery at breakfast time that isn't traditional breakfast fare. Flying Southwest via Terminal 1 at RDU on a recent Saturday morning, we were happy to find this local fave.
They take your order at the register, then cook it up and holler when it's done. Both of us had small cheeseburgers and we shared an order of fries. I made the mistake of getting too much stuff on mine...was tasting too much like salad on a bun, but that was a simple fix...simply took some of the lettuce, tomato and onion off and ate them on the side.
I will say that without waiting outside with smoke all around, it's not the TRUE Char-Grill experience. But it comes as close as can be inside an airport, and it's a nice true-Raleigh option for travelers.
