Time Out says
Take the Keisei line less than 10 minutes from the Skytree and you'll be at Nonbe Yokocho, first founded as the 'Tateishi department store' around 1955. Its current incarnation hosts around a dozen eateries and izakayas, spread out over two alleys. The area may look rather drab at daytime, but most of the shops actually have very interesting interiors. Make sure to investigate side streets.
