Yeah, you're in an airport.  Yeah, you're a captive audience.  No, you don't need to eat a hamburger.  This is America's friendliest airport (they told me so on the brochure) and there are a few decent options in the various wings of the terminal.  This isn't the usual sit-down restaurant place, but more of a fast food counter serving their usual pizzas.  Takes a few minutes, but you'll get fresh and tasty pizza and you won't be disappointed.  I mean, you're in an airport.
