The name is a bit misleading, but this Chinese-American fusion dish is classic STL. Its origin is mysterious, but across the city you'll find white bread filled with egg foo yung (a fried, savory egg patty), mayo, lettuce, tomato, and dill pickles. You'll find this cheap eat (seriously, it's usually under $4!) at Chinese restaurants around the city, but Old St. Louis Chop Suey is a favorite. Add on a piece of duck or pork for something extra special!
