Looking back, my wife has been shopping at Minsun Store for at least six years. But I only just realized they're not yet listed on Yelp. This is probably because they serve a niche market. It seems like a one-man operation. He stocks various frozen and dried Korean grocery items. My wife considers them to be of high quality. Some of them are difficult to obtain elsewhere on Oahu.
Also, the storefront sign is in Korean, and it doesn't even say "Minsun." Instead, it advertises a Korean specialty product, and so the non-Korean-speaking public may have no idea what sort of business this is from the outside.
Yesterday, for instance, my wife picked up several items. What stood out for me was what looked like slender, long, dried roots, which my wife took home to boil and make a sort of medicinal tea. It had an interesting taste. I later found out that it's "Hwanggi" (astragalus root).
The other was a fish she called "Nogari" (partially dried Alaska pollock), which she explained had been partially dried and later frozen. She prepared some this morning with a special sauce she made. It was a tasty treat served with rice.
Up until now, I've mostly been accompanying my wife on some of her shopping trips to this store. I don't personally know enough about the items and have never had personal interactions with the owner himself. He seems cordial and very helpful when speaking in Korean with my wife.
Update: Today is Sunday and I went back alone to at least take a photo of the entrance. When I arrived there, the store was open, so I walked in and explained to the owner that I had been there with my wife yesterday and that I wanted to take photos for a Yelp review that I had started this morning. I reminded him of two of the items my wife had purchased and asked him to show them to me again so that I could take photos of them.
I confirmed that he's open seven days per week, generally from 9 am to 5 pm, except when he closes for lunch, and that on Sundays, he may be out for a few hours for church activities. However, there are times he goes on "vacation" to Korea to pick up goods for sale. read more
