Just west of the Loop, the city’s gregarious Greektown is centered around Halsted Street between Jackson and Washington boulevards. Sizzling platters of flaming saganaki and exuberant shouts of “Opa!” are typical sights and sounds at restaurants here. The area is most active at night, when the restaurants fill with diners, often large Greek families and groups of friends, creating a festive atmosphere. A bonus here is free valet parking at many of the restaurants. www.greektownchicago.org.
