If you visit Gwangjang Market, I recommend trying a variety of street foods. In particular, Yukhoe and Bindaetteok are must-try dishes. Be sure to visit 'Jeju Wit Market-Bar' located inside the market. You can experience a trendy rooftop bar amidst the traditional market atmosphere, and enjoy a refreshing beer with special snacks. From the Jeju Wit Market-Bar rooftop, you can admire the night view of Namsan Tower, so I recommend visiting around sunset to enjoy a beer with the beautiful scenery.
