As the speakeasy sister to Chicago’s acclaimed Gilt Bar, The Library is accessed through a side door and a flight of stairs. The secret room boasts a delightfully dark collection of velvet booths, antique books and vintage chandeliers, transporting patrons to a different time. The Gilt Bar is known for its fantastic food and the same menu is available downstairs, with dishes like black truffle mozzarella sticks, handmade pastas and a must-try steak tartare.
