We're at the Sky Lounge South now, since it was the only thing open when we arrived off of ORD-HND TIAT would have closed to PP shortly after we got there and the other lounges didn't open until 5:30am according to a sign (or 6am according to the oneworld lounge finder)

It's not the most glamorous, but there was no wait for a shower and it's pretty empty, so it has that going for it. The food is edible at least.

As stated in the PP app entry is near gate 108; it's past the 7-11. Restrooms and showers are on the 3rd floor but the rest of the lounge is on the 2nd floor, accessible only by a single elevator. Shower was adequate -- great water pressure -- but the actual space is tiny (just the shower and a sink, no commode) and there's nowhere to sit.
