Pros:
This definitely ranks among the best 9-holers in the chicago area. I was familiar with this area before the course was put in, and thought there was no way a decent course could have been installed on such a small tract of land, but the course designer did a fantastic job creating a challenging, enjoyable course.
This course has a really diverse range of shots, all of which are challenging in unique ways. There are short technical shots, long bombs, and some tough mid-range shots.
All of the little things you look for in a course are here: great signs posted on wood posts, nice concrete tee pads, a course map by the first tee, and garbage cans at every hole.
The landscaping here is impeccable. I've seen work being done on this course on multiple occasions, and it shows. All of the trees are well trimmed, loose branches are removed, the creek that runs along the 9th fairway is lined with rocks, etc.
This course is harsh on RHBH players and isn't a beginner friendly course, but you can really improve your game by playing here.
Cons:
In a few spots the navigation gets confusing. Walking from #5 to #6 you actually pass the tee for #9, but a "next tee" sign is present, so this isn't a huge problem.
Parking could be an issue at times. This course shares a lot with a large soccer facility as well as overflow parking for events at the Oak Brook Park District facilities on site. 9 out of 10 times this isn't an issue, but it's an inconvenience if you come at the wrong time.
A few holes have spots where it is pretty easy to lose a disc, namely #5, which has thick grass on both sides of the fairway and a few large pine trees that have potential to eat a disc as well.
As with most good courses in the suburbs, this place gets very crowded at times, but most of the people I've seen here are pretty respectful of course etiquette.
Other Thoughts:
The course is located on the grounds of the Oak Brook Park District, so it should be easy to find. Once you turn into the park district, you take the first right after the baseball field and follow the road until you see the soccer fields. The course is across the road from the soccer fields and the sign and first tee are visible from the lot.
