About Chicago
City overview
Chicago rises on Lake Michigan at the mouth of the Chicago River, with the Loop, Magnificent Mile, Wicker Park, Lincoln Park, Pilsen, Hyde Park, and lakefront neighborhoods giving the city its architecture, music, food, and museum range. The elevated L, river bridges, and 1871-fire rebuilding story make the urban form as important as any single attraction.
Food & drink
Chicago food arguments start with deep-dish pizza versus tavern-style thin crust, then move to Italian beef, Chicago-style hot dogs, jibaritos, pierogi, and Garrett popcorn. For a first route, use West Loop restaurants, Pilsen taquerias, Chinatown around Cermak, and the Maxwell Street Market on Sundays.
