W Chicago - City Center 
Star Service
Oyster
Fodor's
Star Service "Part of the hip nature of this hotel, and the W brand, is the all-encompassing lifestyle assault that includes an encoded lexicon, which can be confusing for newbies: Living Room means lobby, Welcome is front-desk staff, Style is housekeeping, Sweat refers to the gym"
Oyster "The hotel has an on-site restaurant, a lively bar and lounge, a host of meeting and event rooms, a business center, and a modern gym"
Fodor's "Head to the third floor to access FIT, their 24-hour gym"
