Black, white and orange are the tricolore of ‘Watanabe-ism.’ Black represents faith that cannot be tainted; white, the freedom to become any colour; and orange, the flame manipulated by the chef. On offer here is a fusion of French and Edo food cultures. Sobagaki is emulsified using French techniques; local Japanese elements include kaminari-okoshi, a roasted and flavoured mochi cracker; and monaka, a sweet of azuki bean paste sandwiched between crisp wafers. Watanabe-ism has deep roots in Asakusa-Komagata.
