The sweet chatter and long lines streaming out of this quiet storefront on the eastern slope of Capitol Hill are a bit jarring. But, the Coaston sisters' urban soul food lets locals experience a real down-home time. If the artfully presented platters of Creole Gumbo with cornbread, or Buttermilk Fried Chicken with collard greens don't fulfill those Southern cravings, then maybe the multi-tiered chocolate cake or the cream-slathered strawberry shortcake will. No credit cards or reservations are accepted. Beer and wine are served.
