Yosinui Haru Main Branch is a small cafe in Ulsan that sells bubble tea, other drinks, and bungeoppang. Taro bubble tea and milk tea are the signature items, and pearls can be added at no extra cost. The pearls are chewy and the drinks are served in large portions, with a menu broad enough to suit different preferences. The shop is small, so on weekends it draws enough customers that people line up.
