A city known for big business just got rocked. Chicago’s new Hard Rock Hotel has turned a historic mid-rise into a 381-room memorabilia-stuffed lodging.

For entertainment, there’s the trendy China Grill and a lobby bar serving until the scary hour of 2 a.m. Shake, rattle, and roll during your next Chicago stop. Rooms from $169.
