Guju Hongdae is an izakaya bar in the alleys of Hongdae that serves food alongside sake and highballs. Its signature dish, Jingyeogui Guju Donut, comes in a spicy broth with thinly sliced beef and bean sprouts, and the menu also includes a crab shell crab salad. The izakaya-style space is not too loud, so it is easy to hold a conversation and pair drinks with sake and highballs. Because it sits inside an alley, the entrance is not immediately visible.
