The St. Regis Chicago

"Glorious views (it's in the tallest building in the world by a female architect, after all) meet impeccable service and a world-class spa—what more could you ask for? A butler for every room (even in the entry-level category) means you don't need to lift a finger during your romantic retreat. But, their main draw? A romantic couple's spa day for two. Schedule the three-hour Relax Together (featuring either a facial or full body scrub followed by a 90-minute massage) or Be Well Together (a private meditation or yoga session followed by a 90-minute massage) treatment—you and your beau are sure to leave relaxed and rejuvenated. Both treatments also come with customized refreshments and a post-treatment gift."

"Chicago (and, let’s be honest, the world) has been waiting for this undulating tower by Jeanne Gang—the tallest building in the world by a female architect—to open for years, and the wait was worth it: Glorious city, lake, and river views, a stellar hotel gym, two restaurants, a world-class spa with an indoor pool and outdoor terrace, and a butler for every room (even in the entry-level category), all set in an easily accessible corner of downtown conspire to truly raise the bar on what a city boutique hotel can be. Bring your workout clothes. The roughly 12,000-square-foot Athletic Club is free to guests and has every brand and type of machine you love. There are also three group fitness rooms and a set schedule of classes, from yoga to mat Pilates. Sweat it out, then jump in the pool." - CNT Editors

"If you’re looking to splurge, the St. Regis Chicago Hotel has amazing waterfront views, two excellent restaurants, nightly champagne sabering, and the city’s only Forbes 5-star spa." - Samantha Nelson

"You’ll find one of Chicago’s newest luxury hotels at the edge of Lake Michigan. The St. Regis Chicago soars more than 100 stories, making it the third-tallest skyscraper in the city. This is an ideal home base for exploring the city’s top museums or sampling some of the city’s best Japanese and Italian fare. The St. Regis is home to the sushi restaurant Miru and Tre Dita, a Tuscan steakhouse from chef Evan Funke." - Meena Thiruvengadam
