Goodness Club Seoul is a coffee roastery in Haebangchon that sells focaccia sandwiches, vegan cookies, desserts, and drinks. The tuna avocado sandwich and the house-made focaccia are the main items, and the coffee is brewed strong. The shop has been operating for about three years and was only recently added to Google Maps. The sandwiches are filled generously by the owner, so the portions are large.
