I have been to many of the asian grocery stores around here. being that I am Chinese myself, and this Korean grocery store is by far my favorite.
Unlike the Chinese supermarkets around here, which are usually not that clean and smells like fish, Hankook is VERY clean, like your good ol' American Safeway, and has an amazing selection of food that you can't easily find elsewhere, especially important Asian/Korean goods, including produce, pre-marinaded meats, freshly prepared korean condiments, noodles, canned food, asian drinks, and fresh sashimi fish. The produces/meats are a lot cheaper than American grocery stores, and just as fresh.
They even sell (imported from Korea) clothes, shoes, stationaries, CDs, cosmetics (Shiseido/Lanaige), and gifts in small boutiques scattered around the store.
