The lounge in the Camino Real Hotel, southeast of Polanco, has a sophisticated crowd and mellow music. Lighting and overall color schemes are, as you probably guessed, blue-tinged. There are several seating areas; furnishings are eclectic but are heavy on mid-century modern pieces. One area has a transluscent floor that's lit from below and set over water–very cool and blue.
