Gardens Go Underground

Now, this is major re-purposing. The very tunnels that, 70-something years ago, sheltered London's residents from German bombs are now home to hydroponically grown families of herbs and vegetables. Explains one of the entrepreneurs whose project this is, "We can control the light. We can control the heat. We can control the airflow down here. So it kind of all works in terms of a growing environment, and we don't have to build a greenhouse in the center of London." The taste, apparently, is superior, but I am curious about one thing. Is there any nutritional value to plants grown under these conditions? (video): https://www.youtube.com/watch?v=1PPLWvWSf4w
   And speaking of re-purposing and London, how 'bout a café in an old public restroom? No? Even if it was scrubbed down really, really well?: http://grist.org/list/two-guys-in-london-opened-a-coffee-shop-in-a-mens-bathroom/
