Is it decrepit, or "shabby chic"? Hard to say. There is a similar lone antique shop in a run-down building I used to visit occasionally on 4th street in Coeur d'Alene, Idaho. It's about a block north of Capone's, if you ever happen to visit. I know that block has been slated for low-income housing and combined-use commercial construction for well over a decade, but as far as I know, nothing has happened yet and it is still there.
Shabby chic sounds better doesn't it :) It's a pretty unusual place. They have torn down everything old around here... it's pretty depressing how they changed the main street.
