A good croissant is hard to find in Seoul, and even harder to find outside of well-heeled districts that import French patissiers. Hongdae's The Old Croissant Factory gives the Seorae-maeul French District a run for its money. Their croissant has a flaky, but not burnt, exterior that you can hear when you bite, light and tender layers inside, and a milky, buttery smell. We’re not huge fans of their variations on the original (one with swiss cheese melted on the top, and another with chocolate and sprinkles), but if you’re looking for variety they also sell scones and pain au chocolat. There are a few seats available, so you can sit down and enjoy of cup of Harney and Sons tea with your pastry.
