Many celebrities have been seen at the Absolute Spa at the Century, so it's obviously good at what it does. Rated the number one day spa in the city, it has 8,000 square feet of luxurious pampering space. Italian marble, murals and other touches make the surroundings as relaxing as the services. Treat yourself to a massage (an hour) or a dip in the ozonated pool, meditate in the eucalyptus steam rooms ('Fatigue Fighter' treatment) or a deluxe makeover (45 minutes).
