John G. Shedd Aquarium
The Shedd is a city treasure and well deserving of its title as world's largest indoor aquarium. A mix of standard aquarium tanks and elaborate new habitats, this marble octagon building is filled with thousands of denizens of river, lake, and sea. The only problem with the Shedd is its steep admission price. You can keep your costs down by buying the "Aquarium Only" admission, but then you'll be missing some of the most stunning exhibits.The first thing you'll see as you enter is the Caribbean Coral Reef. This 90,000-gallon circular tank occupies the Beaux Arts-style central rotunda, entertaining spectators who press up against the glass to ogle divers feeding nurse sharks, barracudas, stingrays, and a hawksbill sea turtle. New technology includes an enhanced sound system and a roving camera connected to video monitors mounted on the tank's periphery, which gives visitors close-ups of the animals inside. It's worth sticking around to catch one of the daily feedings, when a diver swims around the tank and (thanks to a microphone) talks about the species and their eating habits.The exhibits surrounding the Caribbean coral reef re-create different marine habitats around the world. The best is Amazon Rising: Seasons of the River, a re-creation of the Amazon basin that showcases far more than fish (although you'll get to see some sharp-toothed piranhas as well).You'll pay extra to see the other Shedd highlights, but they're quite impressive, so I'd suggest shelling out for at least one. The Oceanarium , with a wall of windows revealing the lake outside, re-creates a Pacific Northwest coastal environment and creates the illusion of one uninterrupted expanse of sea. On a fixed performance schedule in a large pool flanked by an amphitheater, a crew of friendly trainers puts dolphins through their paces of leaping dives, breaches, and tail walking. Check out the Oceanarium schedule as soon as you get to the Shedd; seating space fills up quickly for the shows, so you'll want to get there early. If you're visiting during a summer weekend, you may also want to buy your Oceanarium ticket in advance to make sure you can catch a show that day. The newest signature exhibit is Wild Reef -- Sharks at Shedd , a series of 26 interconnected habitats that house a Philippine coral reef patrolled by sharks and other predators. The floor-to-ceiling windows bring those toothy swimmers up close and personal (they even swim over your head at certain spots).If you want a quality sit-down meal in a restaurant with a spectacular view of Lake Michigan, check out Soundings, right there inside the aquarium. There's also a family-friendly cafeteria. Allow 2 to 3 hours.

Frank Lloyd Wright Home and Studio
For the first 20 years of Wright's career, this remarkable complex served first and foremost as the sanctuary from which Wright was to design and execute more than 130 of an extraordinary output of 430 completed buildings. The home began as a simple shingled cottage that Wright built for his bride in 1889 at the age of 22, but it became a work in progress, as Wright remodeled it constantly until 1911 (he left there in 1909). During this highly fertile period, the house was Wright's showcase and laboratory, but it also embraces many idiosyncratic features molded to his own needs rather than those of a client. With many add-ons -- including a barrel-vaulted children's playroom and a studio with an octagonal balcony suspended by chains -- the place has a certain whimsy that others might have found less livable. This, however, was not an architect's masterpiece, but the master's home, and every room in it can be savored for the view it reflects of the workings of a remarkable mind. The Home and Studio Foundation has restored the residence and studio to its 1909 vintage. Allow 1 hour for the tour, more time if you want to browse in the bookshop.

Lincoln Park Conservatory
Just beyond the zoo's northeast border is a lovely botanical garden housed in a soaring glass-domed structure. Inside are four great halls filled with thousands of plants. If you're visiting Chicago in the wintertime, I can't think of a better prescription for mood elevation than the conservatory's lush haven of greenery. The Palm House features giant palms and rubber trees (including a 50-ft. fiddle-leaf rubber tree dating from 1891), the Fernery nurtures plants that grow close to the forest floor, and the Tropical House is a shiny symphony of flowering trees, vines, and bamboo. The fourth environment is the Show House, where seasonal flower shows are held.Even better than the plants inside, however, might be what lies outside the front doors. The expansive lawn with its French garden and lovely fountain on the conservatory's south side is one of the best places in town for an informal picnic (especially nice if you're visiting the zoo and want to avoid the congestion at its food concession venues).The Lincoln Park Conservatory has a sister facility on the city's West Side, in Garfield Park, that is much more remarkable. In fact, the 2-acre Garfield Park Conservatory, 300 N. Central Park Ave. (tel. 312/746-5100), designed by the great landscape architect Jens Jensen in 1907, is one of the largest gardens under glass in the world. It's open 365 days a year from 9am to 5pm. Unfortunately, a rather blighted neighborhood with a high crime rate surrounds the conservatory. If you want to see it, I recommend driving rather than public transportation.Allow a half-hour for the Lincoln Park Conservatory.
