Note that the E terminal AC does serve the same food, but due to size limits some. So you'll find the same basic menu, but not all the features, sides, etc. This is unlikely to affect you unless you have a flight out of that terminal and decide to head there to be closer (E is on the way to the satellite terminal, so not exactly a logical stop for anyone else).

A , C, and D are the largest and best. D is nicest, and A is also big and bright. D is always more crowded since many international flights arrive and depart there. However, I like C (this is not a popular choice), even though it's more dated and darker. It's sprawling, and feels less crowded to me, and the dimmer lights in some areas are welcome when I have too many hours to rest. but more crowded. B is not one I love, and is too far from many of the B gates to be helpful. A, C, or D are all fine. The fact there are so many means less crowding unless you insist on a particular lounge, so that is nice as well!
