SOUTH LOOP. This beautiful main branch of Chicago's Public Library system opened in 1991. Built in Neoclassical style with high columns and vaulted ceilings, the building soars 10 stories and is capped by a majestic Winter Garden. The collection includes nearly 2,000,000 books and almost 14,000 periodicals. After touring the facility, treat yourself to a snack at the café (Mon-Sat 11am-3pm), which serves light lunches, tea, and coffee and offers a terrific view of the South Loop. Guided tours are available. EL: Brown, Purple, and Orange Lines to Library Station
