The E concourse "Premium" lounge has superior food and beverage (especially Taittinger) than any Admiral Club I've visited in the past 25+ years. I always make a point to use it instead of the evolving D concourse alternatives whenever flight schedules and gate assignments allow. The fixtures and furnishings have changed very little since the late 80s when E was the Latin America/Caribbean gate area for American. When I have Flagship Lounge access I opt for that because there is no comparison, it is vastly superior to the concourse E Premium lounge.
