Gachi CSA which delivers local organic & eco friendly food baskets to expat members' doors every week. CSA stands for Community Supported Agriculture which you may already be aware of. It's a mutually supportive relationship between producers and consumers based on trust.
It’s not easy to find organic food in common markets or little pricy in Korea. There are a many Korean CSAs but this is the only one directed towards the expat, foreigner community and offers also vegan baskets and vegan bread! The bread is awesome.
Delivery in any city.
They are conscious of local farmers, and healthy food and environmental concerns.
