Okay, I'll give you the shopping malls and some chain food joints. That you'll need a car to get to. And yes it's a clean tidy burb that can be mistaken for many others in the U.S.
Now for the comments from L.A. user, best for beaches? The beaches are in Chicago! And some other comment, there would be no Winnetka, without Oakbrook! ...

Maggiano's Little italy is not one of the best restuarants in Oak Brook, I know this because I work in Oakbrook Terrace,and definitely far not the best in the Chicagoland, so don't be misinformed by the review you have read. Actually when I went to the one in Oak Brook their lasagna was far from being one of the best, just about average or ...

The absolute best lasagna on the planet! Don't miss this. There are several locations throughout Chicagoland. We ate at the one downtown, but I'm sure the food is the same at each. You can't beat the ambience of the downtown location though.

Oak Brook rocks!! This is the best suburb in America. If it wasn't for Oak Brook there would be no Winnetka. Oak Brook forever! I love it.

This is the best restaurant in Oak Brook in my opinion. The food, wine and service are really excellent, and it should not be missed.

Enjoy, Jim
