I found top Executive lounges in Europe, among the best Hilton Warsaw, Hilton Vienna Danube, Hilton Budapest Castle, Hilton Malta, Hilton Basel (now gone) and many more.
Not just for breakfast offerings but for happy hours selection (sometimes a real dinner), exclusive and stylish environment and personalized service.

I am really shocked by what are you all telling me about US lounges (never been there): why is there such a low level? And why are they closing them?
Is the typical US hotel owner stingy if compared to the european colleagues?
