Did the regular Plaza Premium lounge in D today, no line but the 2 attendants sure take their sweet time checking people in. Food was decent for a lounge but nothing amazing. Highlights are likely the comfy high-back chairs overlooking the concourse which is great for people watching and the barista espresso machine at the bar.

Speaking of the bar, drinks are probably the worst of the D lounges bc the comp alcohol options are similar to Admirals Club but ACs will generally make real cocktails for you as long as it doesn't include their premium liquors. Plaza charges $10-$12 for cocktails like Old Fashioneds, margaritas, cosmos, etc., per their menu (wouldn't shock me if some bartenders will make them for you with the comp liquor but it seems like at least officially you have to pay for those).
