Nick is a familiar face in this fine place because, as he said himself, they don't serve drinks in his office. Maximino, the owner of the place, is also present most of the time.
The music that plays in High Roller's Lounge is very interesting, and personally I find it one of the best tunes in Grim Fandango. If you want to download it you must go to grimfandango.net through the links.
