I met Morimoto Masaharu on the Tokyo Limousine from Narita Airport. Oddly enough, my parents were staying at the same hotel he was, and we met him the next day, also randomly; his manager gave us his 名刺 (meishi=name card), though I should've asked for his signature. I also met Bobby Flay years ago at a NY food show; too bad I didn't have a mango for him to sign.
