Introducing Koko Ramen , our favorite place to get authentic Japanese ramen in Brooklyn, just a short walk from our Flatbush House . Koko has an unassuming exterior, like most of New York City’s gems: Its plastic red door and wooden panelled walls only hint at the magic inside. A yellow sign floating on the roof with a bowl of steaming ramen stencilled on it is your only indication to step inside: Ramen will follow.
