Mugino Oto is a bistro in Kabukicho, Shinjuku, serving food and drink centered on craft beer and natural wine. The menu pairs dishes such as marinated seasonal vegetables, house-made white liver paste with garlic toast, and duck confit soba with alcohol. It is about a five-minute walk from the nearest exit of Shinjuku Station, has six beer taps, and offers counter seats, tables, and a private room. It sits down a set of stairs in an alley behind a karaoke building, which makes it hard to find at first.
