^ In light of the recent negative reviews, I just wanted to offer an opposing view. We stopped into the Naperville Boston Blackie's on Saturday and, generally speaking, enjoyed our dinner there. The burgers are large (with all due respect to other posters, I just don't understand how someone could characterize the portions as "minimal"), the prices are very reasonable ($6-$7 for a burger is not, in this day and age, expensive), and the food is good and, IMO, represents a good value. The service was fairly efficient and better than expected.
I really wouldn't consider it an upscale restaurant -- and my biggest complaint, if I were to make one, would be that the lackluster environment/atmosphere and Route 59 strip mall location are a little off-putting. That, and the overly crowded atmosphere (typical for a Saturday night, probably), probably will keep us from becoming regulars. However, the food itself was very good, and the burgers are easily in the same category as Country House and some of the other west suburban favorites.
