Gwangjang Market is a small area in Seoul where street food is a must try, it offers a plethora of food options that really gives you taste of Korea. I found it through a Netflix show where they featured multiple food stands from the market. The market's food options ranges from raw marinated crab to sundae or Korean blood sausage among other things. They also sell other random assortments like clothes, fabrics, snacks, and other items but they are most known for the food. Personally the best food I bought at the market was the sundae sold by an elder couple in the middle of the street, pajeon (Korean pancakes), and small twist donuts. Many of the places including Netflix featured hand cut noodles place have long lines and stop business when they run out because this is a popular tourist spot.
