Almost anything you can find at the local corner store in Seoul is at Lee's Market. The only thing missing is the soju. The lady running the place was very helpful, finding everything I needed to make my meal. There wasn't a huge mark up on most of their imported goods, you can buy a pack of peppero for the same price as in Korea. The imported soft drinks were a lot pricier, but those are probably a lot more expensive to ship, so it's understandable.
