Where does the food on our plates come from? Who grows it and how does it reach our tables? It's almost impossible to know, even when we're at home cooking for ourselves. Eating out in restaurants is a far greater leap of faith.

No such worries at Roppongi Nouen. This is one place where you can trace what you're eating right back to the very source, and even look at photos of the farmers' faces and fields. Drop in on the right day and you might get the chance to meet them face to face and chat about the merits of organic agriculture.

The idea of hanging out with farmers in the heart of the city — and even chilling with a cocktail in hand by the side of a produce plot — seems improbable at best. To do so in one of Tokyo's main nightlife districts is verging on the surreal.
