Hachitai Yoomaru is a small izakaya on the sixth floor of a building in Sapporo. Its main items are unimaguro maki, assorted hoe, kkoi ponzu muchim, and grilled fish, served with onzake. A Korean menu is available and Korean-speaking staff help with orders, and a potato salad comes with drinks. Arriving without a reservation around 7 p.m. on a Friday can mean the seats are full.
