I have'nt been in Chicago for a long time, but I used to work on the Northwestside and used to eat at Johnny's snack shop (Diner). It was a small place with good food and big portions. The customers were always entertained by the owner and cook with jokes. If this place is still there, I recommend it. They had specials everyday and were only open for breakfast and lunch at least when I used to go to Johnny's like 6 years ago.
