You can't (and shouldn't) miss the Art Institute: The signature pair of bronze lions that flank the museum's main entrance are perfect rendezvous points, and there is always a throng of people sitting on the steps on nice days. Finding the museum is easy -- it's deciding what to see that is hard. Choose a medium and a century and the Art Institute has the works in its collection to captivate you: Japanese ukiyo-e prints, ancient Egyptian bronzes and Greek vases, 19th-century British photography, masterpieces by most of the greatest names in 20th-century sculpture, or modern American textiles. For a good general overview of the museum's collection, take the free "Highlights of the Art Institute" tour, offered at 2pm on Saturdays, Sundays, and Tuesdays.

If you've got limited time, you'll want to head straight to the museum's renowned collection of Impressionist art (including one of the world's largest collections of Monet paintings); this is one of the most popular areas of the museum, so arriving early pays off. Among the treasures, you'll find Seurat's pointillist masterpiece Sunday Afternoon on the Island of La Grande Jatte. Your second must-see areas are the galleries of European and American contemporary art, ranging from paintings, sculptures, and mixed-media works from Pablo Picasso, Henri Matisse, and Salvador Dalí through Willem de Kooning, Jackson Pollock, and Andy Warhol. Visitors are sometimes surprised when they discover many of the icons that hang here. (Grant Wood's American Gothic and Edward Hopper's Nighthawks are two that bring double takes from many visitors.)

Other recommended exhibits are the collection of delicate mid-19th-century glass paperweights in the museum's famous Arthur Rubloff collection and the great hall of European arms and armor dating from the 15th to 19th centuries. Composed of more than 1,500 objects, including armor, horse equipment, swords and daggers, polearms, and maces, the collection is one of the most important assemblages of its kind in the country. (If you do head down here, don't miss Marc Chagall's stunning stained-glass windows at the end of the gallery.)

The Art Institute goes the extra mile to entertain kids. The Kraft Education Center on the lower level features interactive exhibits for children and has a list of "gallery games" to make visiting the museum more fun. When I was a kid, I was entranced by the Thorne Miniature Rooms, filled with tiny reproductions of furnished interiors from European and American history (heaven for a dollhouse fanatic).

The museum also has a cafeteria and an elegant full-service restaurant, a picturesque courtyard cafe (open June-Sept), and a large shop. There is a busy schedule of lectures, films, and other special presentations, as well as guided tours, to enhance your viewing of the art. The museum also has a research library. Allow 3 hours.

Insider Tips for Touring the Art Institute--If you want to enjoy your favorite masterpieces in something resembling peace and quiet, put some thought into the timing of your visit to the Art Institute, a museum so popular that it draws as much traffic as our jammed expressways.

Some tips for avoiding the rush hour: Many people don't realize the museum is open on Mondays; so keep this secret to yourself, and visit when the galleries are relatively subdued. Wednesdays are a close second. Tuesdays tend to draw the masses because the Art Institute is free that day and open late (until 8pm). Try to arrive when the doors open in the morning or else during the lunchtime lull. Another tip: If the Michigan Avenue entrance is crowded, head around to the entrance on the Columbus Drive side, which is usually less congested and is more convenient to the Grant Park underground parking garage. There's a small gift shop near the Columbus Drive entrance, too, if the main shop is too bustling.
