Dirty Trunk
This cavernous brunch cafe not far from Paju Book City looks like a factory on the outside, but inside, it's part library, part botanical garden, part public square. The bakery puts out an incredible selection of baked goods, most of them very sweet, along with unique desserts like a "dirty chocolate s'more bingsu." The coffee and non-coffee menu is extensive, though like their desserts, they err on the sweet side. There's also a dining menu, too, with some decent pasta dishes for the brunch crowd.
