Hidden - as in a door in the wall. No signs - its on the laneway side of 137 (I've attached a pic of the door - can't promise its going to look the same, what with Melbourne's graffitti scene). Beautiful Japanese (not the same as the real thing obviously - but damn close!) gorgeous presentation, and totally fresh. Bento lunch best value.
On a side note, I came here with a group of friends, and they showed us into the tatami room. Private and lovely, perfect for intimacy, or louder groups.
