Biking through the Fulton Mall this week we were struck by how unaffected it appeared to be by the recession and broader downturn in the retail environment. We obviously don’t have any numbers on sales trends at any of the stores, but we were impressed by the fact that there was only one small store that was empty and only one other For Rent sign on the entire seven-block stretch. This is in marked contrast to the scene on Flatbush and Atlantic Avenues and, well, almost everywhere.
