I went to the lounge yesterday (4/14) at around 5:15 pm, some comments:
(1)it is described as being near gate D4--IMHO, a better description would be as you enter the D1-D12 gate complex, it is immediately to the left [gate D4 is the closest numbered gate, but not that close.]
(2)the décor is very nice, and they have some nice hot dishes, and sandwiches--but nothing spectacular. The deserts consisted of brownies and chocolate chip cookies, which they did not restock too often. Their liquor selection is mediocre and you must request it from the bar person (there are other airline lounges which have self-service liquor^.)

[The man ahead of me tried entering the lounge based on his One World status (AA system), they wanted him to pay $50, he wound up talking to a supervisor--I don't know if he was allowed in without paying.]
