E-Mart: Korean Mega Store
For 5-day stay in Jeju island, we visited here three times, almost every night. Nothing much, but it was fun browsing Korean foods. Most parts are just like Japanese mart, Aeon, but then there are some very Korean specific items.
They have good selection of dried seafood. Great companion for beer lovers.
And of course, this is famous Korean Gochujang. In Japan, we have one or maybe two kinds of these in supermarket, but E-Mart had entire shelf for this.
Green lettuce for Korean BBQ. If I ever live in Korea, this would be my daily item. 🙂
