After your treatment, you can relax in the coed lounge or head to the fitness center packed with brand-new TechnoGym equipment.
Bellagio Rating: 5.0 Pearls
Grandiose is the name of the game at Bellagio: the luxe 55,000-square-foot spa has 56 treatment rooms and a 6,000-square-foot fitness center. Male clients receive equal attention here, like in the separate barber room where guys can opt for a straight-razor shave. There's a fee to use the fitness center, but that includes access to the spa's four whirlpools, eucalyptus steam room, and sauna. Also, it's worth coughing up an additional $30 or so for a treatment inside the spa's candlelit meditation room.
