America's third largest city - behind New York and Los Angeles - is Chicago, and millions of visitors flock there each year to sample its museums, sporting events, and deep-dish pizza. Chicago is located in northern Illinois and curves around Lake Michigan, with the Chicago River snaking through its center. The lake is central to the city's prosperity and climate, regulating temperatures so that it is warmer in winter and cooler in summer. Chicago boasts nearly 30 public beaches along its shores, as well as several parks and green spaces, including Lincoln Park , which is second only to New York 's Central Park in the number of visitors it attracts each year.
Chicago 's Navy Pier is one of its biggest attractions. At 3,000 feet long, the pier, which extends along Lake Michigan , houses several restaurants, shops, and museums. It is also home to a 150-foot tall Ferris Wheel.
The Magnificent Mile is another of Chicago 's treasures. This upscale street fronts the Chicago River and is home to several high-end retailers, five-star restaurants, and luxury hotels. Chicago is one of America 's most ethnically diverse cities, with a large population of African-Americans, Poles, Germans, Swedes, Italians, and Irish, among others. This mix of cultures is reflected in the city's distinct and varied cuisine.
