During your Chicago vacation, don't miss these great establishments and attractions:

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.

Sears Tower Skydeck
First Sears sold the building and moved to cheaper suburban offices in 1992. Then the skyscraper got an ego blow when the Petronas Towers in Kuala Lumpur, Malaysia, went up and laid claim to the title of world's tallest buildings. (The Sears Tower has since put up a 22-ft. antenna in an attempt to win back the title.) Tallest-building posturing aside, this is still a great place to orient yourself to the city, but I wouldn't put it on the top of must-see sights for anyone with limited time (and limited patience for crowds).The view from the 103rd-floor Skydeck is everything you'd expect it to be -- once you get there. Unfortunately, you're often stuck in a very long, very noisy line, so by the time you make it to the top, your patience could be as thin as the atmosphere up there. (Come in the late afternoon to avoid most of the crowds.) On a clear day, visibility extends up to 50 miles, and you can catch glimpses of four surrounding states. Despite the fact that it's called a "skydeck," you can't actually walk outside. Recent upgrades include multimedia exhibits on Chicago history and Knee High Chicago, an exhibit for kids. The 70-second high-speed elevator trip will feel like a thrill ride for some, but it's a nightmare for anyone with even mild claustrophobia. Allow 1 to 2 hours, depending on the length of the line.

Auditorium Building and Theatre
A truly grand theater with historic landmark status, the Auditorium is worth a visit to experience late-19th-century Chicago opulence. Designed and built in 1889 by Louis Sullivan and Dankmar Adler, the Auditorium was a wonder of the world: the heaviest (110,000 tons) and most massive modern edifice on earth, the most fireproof building ever constructed, and the tallest building in Chicago. It was also the first large-scale building to be electrically lighted, and its theater was the first in the country to install air-conditioning.The 4,000-seat theater, which today is the scene for Broadway touring musicals, is a marvel of visionary design and engineering. Originally the home of the Chicago Opera Company, Sullivan and Adler's masterpiece is defined by powerful arches lit by thousands of bulbs and features Sullivan's trademark ornamentation -- in this case, elaborate golden stenciling and gold plaster medallions. It's equally renowned for otherworldly acoustics and unobstructed sight lines. In the days when the Auditorium was the leading theater of Chicago, the hydraulically operated stage could be lowered from view, creating a ballroom capable of accommodating 8,000 guests.During World War II, the building sheltered GIs, and its theater stage was turned into a bowling alley. The theater reopened in 1967 following a $3-million renovation made possible through the fundraising efforts of the nonprofit Auditorium Theatre Council. Remnants of the building's halcyon days remain. Don't miss the lobby fronting Michigan Avenue, with its faux ornamental marble columns, molded ceilings, mosaic floors, and Mexican onyx walls. Another inside tip: From the Roosevelt University entrance around the corner on Michigan Avenue, take the elevator to the school's 10th-floor library reading room and have a look at what was once the city's first top-floor dining room. Its palatial, barrel-vaulted ceiling, and marvelous views of Grant Park and the lake will make you want to brush up on your Dewey Decimal System.The best way to see everything is to take a 1-hour guided tour, offered on Mondays between 10am and 4pm (call tel. 312/431-2354 to make reservations). Tours cost $6 for adults, $3 for seniors and students.Allow a half-hour, 1 hour if you take the guided tour.

Four Seasons Hotel
Consistently voted one of the top hotels in the world by frequent travelers, the Four Seasons offers an understated luxury that appeals to publicity-shy Hollywood stars and wealthy families. Although the hotel has every conceivable luxury amenity, the overall look is that of an English country manor rather than a glitzy getaway. The real attraction here is the service, not the decor.The city's tallest hotel, the Four Seasons occupies a rarefied aerie between the 30th and 46th floors above the Mag Mile's most upscale vertical mall. The elegant rooms have English furnishings, custom-woven carpets and tapestries, and dark-wood armoires. Each has windows that open to let in the fresh air. Bathrooms boast such indulgences as a lighted makeup mirror, oversize towels and robes, scales, and Bulgari toiletries. Kid-friendly services include little robes, balloon animals, Nintendo, a special room-service menu, and milk and cookies. The hotel's elegant fitness center and spa exude the same upscale, old-money feel as the rest of the public areas. An 18-foot-high white marble fountain marks the entrance to the opulent Seasons Restaurant.

City Suites Hotel
A few doors down from the elevated-train stop on Belmont Avenue, this former transient dive has been transformed into a charming small hotel. Most rooms are suites, with separate sitting rooms and bedrooms, all furnished with first-rate pieces and decorated in a homey and comfortable style. The amenities are excellent for a hotel in this price range, including local limousine service, plush robes, and complimentary continental breakfast. A bonus -- or drawback, depending on your point of view -- is the hotel's neighborhood setting. Most rooms can be fairly noisy; those facing north overlook Belmont Avenue, where the nightlife continues into the early morning hours, and those facing west look right out over the rumbling El tracks. On your way in and out of the hotel you'll mingle with plenty of locals, everybody from young professional families to gay couples to punks in full regalia. Blues bars, nightclubs, and restaurants abound hereabouts, making the City Suites a find for the bargain-minded and adventuresome. Suites have fridges and microwaves on request. Room service is available from Ann Sather, a Swedish diner and neighborhood institution.

Sofitel Chicago Water Tower
The latest addition to Chicago's already-crowded luxury hotel scene, the Sofitel aims to impress by drawing on the city's tradition of great architecture. French architect Jean-Paul Viguier created a building that's impossible to pass without taking a second look: a soaring, triangular white tower that sparkles in the sun. But the place doesn't take itself too seriously, as you'll see when you walk in the airy lobby and check out the luminescent floor tiles that change color in a never-ending light show. The overall feel of the hotel is European modern; you'll hear French accents from the front-desk staff, and foreign-language magazines are scattered on tables throughout the lobby. The bright, stylish Café des Architects has become a favorite business lunch spot for locals.The guest rooms feature contemporary decor with natural beechwood walls and chrome hardware. All the rooms enjoy good views of the city (but the privacy-conscious will want to stay on the upper floors, where they won't be on display to surrounding apartment buildings). The standard doubles are fairly compact -- but thanks to large picture windows, the spaces don't feel cramped. The luxurious marble bathrooms (with separate tub and shower stall) are quite spacious. The amenities are top-notch. Recognizing that business travelers are the bread and butter of Chicago hotel profits, ample support services exist for working visitors. But this doesn't mean that Sofitel doesn't welcome families; in fact, up to two children can stay in a room for no extra charge (they'll even roll in a portable bed for the kids).
