For Priority Pass users, I just visited the vip lounge at CUZ. The access is before the security check (you must calculate the time at peak hours), at first floor. It was good. No self service but waiters attend you. It's not as big as Sumaq but is bigger than Caral (LIM domestic terminal lounge).

It has access also from the international area, but I couldn't see if it was after or before the security check.
