Great experience here today and only lost a star because of how crowded it was - difficult, but not impossible to find a table. It's located by the D gates (gotta take the sky train from terminal 1).
Service is kind and fast - the food and drinks are self-serve though. There's a full bar with seating and a TV to catch up on sports. There's also a small buffet bar with deliciously wholesome options, including a cold salad bar, fresh fruits, and hot breakfast/lunch options (soups, wild pecan rice, roasted brussel sprouts, quiche, sandwiches). There is also a drinks area with juices, water, hot teas and caffeinated drinks.
