Fantasies of a Dilettante Grocer

I see the old Dilettante Chocolate space on 23rd and Cherry is available for rent, at a very reasonable price!   In some alternative universe, I'd love to buy it and open up a sweet Jane Jacobs-inspired corner grocery store there.  

Alas, I know nothing about the corner grocery business (except for what stories I heard about my grandfather's corner store back in New York), and I'd imagine the regulations and such involved are pretty foreboding.  

Perhaps some other dilettante will read this post and be inspired to give it a shot.
