Probably the largest Korean market in Eastern Iowa (Iowa City area). Also carries some Vietnamese, Japanese, Thai and Middle Eastern products. Many fresh vegetables as well.
I’d guess 98%+ of all Korean ingredients are available here at decent prices for Iowa.
Yes, we’ve been impressed with the selection of goods at Chong’s! One weak point is produce and refrigerated items (sometimes all the kimchi seems very overfermented, and there is moldy tofu or ddeok) but for most kinds of pantry items, it’s great and saves a trip to HMart in Chicago!
