Visited the DCA Centurion Lounge a couple of weeks ago. Somewhat convenient going to the United gates (which I was) but inconvenient to most of AA's gates. Very attractive lounge with friendly and helpful staff. Not crowded at at 9:30am. Hot breakfast buffet roughly the quality of Hyatt House -tiny one bite muffins but full size chocolate croissants. Garlic scrambled eggs and chicken sausages, cut fruit and salad "stuff." Food not worth a detour-not the same quality as the early Centurion Lounges. Maybe evenings are better. But as a waiting area/lounge it's very comfortable.
