I don't see how any storefront business survives Downtown.   Who that doesn't have to would want to go there?   Restaurants can survive on office workers.   Bars can survive on young people so long as they don't become too gang-infested.   Some touristy places can make enough in summer to survive the winter.  But retail other than in the protected confines of a mall has a tough go.    And even in a mall, I suspect the only one making much money is the owner of the mall.   You can get most anything you want south of Dimond and you don't have to deal with drunks, filth, and expensive parking.
