absolitly good idea in busy cities. Actually same like when you visit a 2 ot 3 michelin star restaurant. Or lets say similar. They also have they own garden so most of the vegetables comming fresh from there. Thays why the price is also expensive to eat in these high class restaurants. So the question is how these kind of vegetables or what ever will be expensive? I am lil bit afraid that they wil have a very high price so again just the "choosen ones" can enjoy this kind of innovations.
But the idea is good and the hunt also😉
