"You'll feel like a royal when walking into the chateau-style Waldorf Astoria Chicago, thanks to its Parisian courtyard entrance and pristine lobby. That elegance extends to the award-winning spa, a fourth-floor retreat where guests can experience luxurious downtime with facial and body treatments incorporating premium product from Biologique Recherché (which guests can purchase post-service at the spa’s shop, which also stocks apparel from the likes of Balmain and Lululemon). The team here encourages guests cozy up in robes (courtesy of Frette or Chadsworth & Haig) to enjoy many onsite amenities, including a whirlpool, eucalyptus steam room, dry sauna, indoor heated lap pool, and fitness center, along with snacks and fruit-infused water (and Champagne for anyone celebrating a special occasion). Small groups can also check out the spa terrace, where light bites and drinks are served." - Nicole Schnitzler
