You can go to any Korean video store. There are about a dozen of them in Chicago. Most do not carry subtitled programs.
Hyundai Video 3615 W. Lawrence, 773.588.8737 This large, well-lit store boasts an impressive collection of Korean video (and Chinese and Japanese videos dubbed into Korean) divided, Ã la American video stores, by popularity and genre. A universe of Korean videos is available here -- martial-arts films, love stories, Japanese and Korean TV mini-series, and isolated in a section all by itself, Korean and Chinese adult videos. As you might expect from a store geared to Koreans, the signage is mostly in Korean. However, the proprietor willingly suggests videos to non-Korean customers. Few tapes are subtitled in English and an initial $20 deposit is required. Videos are $1 a day, but if you rent six or more, you may keep the videos a week.
