For airport food, Sammy's is legit. The prices are good (for an airport restaurant), portions are large and the food actually tastes okay.
I got some sort of bacon omelet (the only one on the breakfast menu) and was impressed. My total came out to like $11. Not bad!
Downside: they only had one server working and he was SLAMMED! Poor guy. He did a good job though given that he was the only one waiting tables.
