Just a stone's throw from the Tokyo central fish market, Takeno is a rough-cut neighborhood restaurant that tends to fill up at noon with the market's wholesalers and auctioneers and office personnel from the nearby Dentsu ad agency and Asahi Shimbun (newspaper) company. There's nothing here but the freshest and the best at reasonable prices. Sushi, sashimi, and tempura are the staple fare; prices are not posted because they vary with the costs that morning in the market. Reservations not accepted. Subway: Hibiya Line, Tsukiji Eki (Exit 1); Toei Oedo Line, Tsukiji-shijo Eki (Exit A1).
