Time Out says
In a departure from Tsukiji's usual seaside theme, Yoshizawa Shoten is actually a butcher shop that handles mainly beef – including Japanese black beef. It also sells street snacks, such as Japanese black beef pickled in Saikyo miso, beef cutlets and grilled pork. The Matsuzaka beef minced meat cakes are the pick of the bunch though – made with 100 percent ground Matsuzaka beef for a rich, juicy snack.
