Koi is an izakaya in Seoul that serves aged hoe, futomaki, and Japanese alcohol. The menu includes smoked oyster and chamnamul pasta, tomato chadol suji nabe, and mentaiko omelette, and staff recommend nihonshu to match a preferred taste and aroma. Two separate rooms sit at the back, and the tomato stew can be ordered with added noodles to eat like pasta. Prices run high, which makes it a burden for light drinking.
