Great selection of classic rock and jazz records, with a nice mix of common faire and less widely findable records and cds. Allen, the guy that runs the place, is also super helpful and quite knowledgeable which makes for a good buying experience. A great aspect of this place is the fair pricing.
My one complaint is that the mark up on new vinyl records is a tad high at times, which sometimes makes me debate whether I want to buy a new record here or put the cash in my pocket until I have time to make the trip cross town to Reckless and pay a little less.
Now that Second Hand Tunes in Evanston has closed, Oak Park is #5 in my list of record stores overall in Chicagoland. That puts them up there with the "greats" everyone thinks of when they think of Chicago--Reckless, Dusty Groove, and Dave's, and now, also Bob's Blues and Jazz Record Mart (Same Bob as the, now closed, Jazz Record Mart). Definitely worth the trip to check them out!
