With the wealth of places serving fried fish, fried chicken, ribs and hamburgers on the South Side, A.P. Deli Chicago's #1 Corned Beef specializes in, well, you know, corned beef. Huge chunks of corned beef are constantly run through a slicer behind the order taker, tempting the customer to sample this specialty. Roast beef, the natural complement to corned beef, is also featured here. They are all served on wheat, rye or white bread. A.P. doesn't stop with just corned and roast beef. Other specialties include the Philly steak, hoagies and hamburgers. Desserts are also quite interesting. The selections: Mississippi mud cake, raspberry cheesecake and carrot cake; all cost $3. There are no seats at A.P. Deli. You will find yourself using the long counter in the waiting area underneath the window for support while you wait.
