It is what it is. If you want "real" food in terminal C this is where you will find yourself. Then you might question if fast food wouldn't have been the better option?
I generally skip fast food because of the unhealthy but in this case I am pretty darn sure my Omelette was on par with Popeye's or whomever else was next door.
The flavours were tasty (it's cheese sauce and eggs though-not much to mess up) the coffee was coffee and the service was mostly there. I mean she wasn't friendly but she didn't glare either.
It's not worth the money but you're in an airport so that's no surprise.
I guess you just have to ask yourself "Do I have time to kill, do I want to feel like I'm in a restaurant? Do I want to see Sammy Hagar's face over and over again?" If you answered yes to any of these questions...
