My Chicago favorite (and now Worldwide favorite) is Morton's... Sullivan's is probably the closest thing to Morton's in Naperville.
I have had "Great" experiences... and "Good" experiences with the food quality and preparation.... Service has always been either "Good" or "Average" depending on how busy the restaurant seems to be on any given evening.
It is good enough to keep me from driving an extra 45 minutes to the nearest Morton's most of the time.
