When I think of a champagne bar it conjures visions of elegant couples leisurely enjoying a bottle on the beaches of the Côte d'Azur. Instead, Laguna is a haven for fat old men to inhale rancid cigar smoke and chase it with Coors Light.
For some reason they allow you to smoke cigars in the bar area. Maybe they are trying to attract every douche bag and creeper in Vegas. If so, it's definitely working.
This place is a mecca for cancer and run down hookers, but apparently they also serve champagne.
