When ordering at Chengdu Impression, diners should prioritize authentic Sichuan specialties like the dry chili chicken, which is widely praised for its crispy texture and fiery spice level, and the mapo tofu, often cited as one of the best versions in Chicago for its numbing "mala" flavor. Popular appetizers include the dan dan noodles, spicy Sichuan wontons, and Zhong’s dumplings, which feature a unique sweet and spicy sauce. Other highly recommended dishes include the crispy eggplant, Sichuan string beans, and twice-cooked pork belly. For those seeking traditional Sichuan flavors, the spicy boiled fish and cumin lamb are standout choices, while classic favorites like crab rangoon and scallion pancakes are also frequently enjoyed. To ensure an authentic experience, many reviewers suggest avoiding standard American-Chinese staples in favor of the menu's more specialized Sichuan offerings.
