Located at Gate D20, I make a point to go here during layovers, even if I'm connecting out of another terminal. This place is worth a short jump on the Skylink if you've got the time. While it's the great beer selection that first drew me in, it's everything else that keeps me coming back. They have a simple but excellent menu, some of the friendliest staff around, and for being located in an airport, the atmosphere is about as good as it gets. The roast beef and cheddar sandwich, with a hint of spicy horseradish and arugula, is my personal favorite. It goes very nicely with a creamy pint of Guinness. No one likes layovers, but this place sure makes them a lot more tolerable.
