1 star for filling, 1 star for quick.  Not much else to recommend about the place.  The breakfast menu is fairly limited, French toast or egg sandwich on roll or English muffing.  The roll I got was stale and the bottom absolutely caked in flour that I had to scrape off using the plastic knife as a putty knife.  \n\nStill, the location is right at the top of the escalator at D terminal, so whether you're heading left or right to your gate, it's convenient.  Quick too. I paid, squeezed through the crowd at the self serve drink fountain, sat and almost immediately had the food brought over to the table... almost before I had time to put the service number in the holder.\n\nThe egg was real, plenty of American cheese, and fairly crisp bacon.  I got tired of the stale roll halfway through the sandwich, and used the bottom of the other half as a plate to eat the egg, cheese, and bacon off of.\n\nIf you want something quick and filling, this is your place.  I'm not sure what other options there are in the terminal, but next time I'll continue looking before returning to Ruby's.
