There's a few decent spots in Tokyo. I've been to one in Nishi-Ogikubo (I think?), one in Naka-Meguro, one in Daikanyama (with an Iron Chef chef, no less), and another in... Omote-Sando was it?

Two of the four were great (Daikanyama one and Omote-Sando one), and the other two were very good. If you ever wanna go sometime when you're in Tokyo, lemme know and maybe we can arrange an outing with some of the Mexican fans. :)
