Simply put: gate agents are awesome! Some of the best in the system.
Security: ehhh....you know how when you don't have anything nice to say, don't say anything at all? Well, I'll stay mum about this.
Food selection: fair.
Seating: not enough.
D gates (used for regional jets) are cleaner and nicer than C gates (737s and Airbus primarily, although sometimes the RJ's come here too).
Of all the airports I fly through for work, this is not one of my favorites.
