It appears that the local, healthy food movement has hit Korea just as hard as it has the United States. It seems like everywhere I look these days on Jeju, restaurants and supermarkets are advertising their local meat and produce. While it is nice to be able to get fresh, local food in restaurants and supermarkets, I still prefer buying food at farmer's markets. Fortunately, Jeju supposedly has one of the largest outdoor farmer's markets in Korea. Not only is it a great place to get food, but it also an amazing cultural experience as well. Some of my fellow English teachers and I always make it a point to visit it every week.
Jeju's farmer's market is just known as the 5 Day Market amongst the expat community of English teachers here in Korea. This is because the market is held on any day that ends in a 2 or 7, so every five days. You can find everything here at reasonable prices. I buy vegetables, meat, spices, and seafood here on a regular basis. Even though a lot of the farmers don't speak English that well, I have been able to form a decent relationship with them just by showing up every week and always buying the same amount. The market even sells plants, pets, clothes, and furniture. On occasion, I have found some great deals on clothes and plants here as well. My apartment is now decked out in bonzai and cacti!
