A thread of the original Catfish Corner’s Southern legacy continues on at this prime Central District spot via fried chicken atop old-fashioned thin waffles, the kind with tiny squares. The kitchen coaxes heroic amounts of personality from boneless, skinless chicken breasts with help from seasoning that’s sufficient for grown-ups and mellow enough for the many (many) kids in the room. Replacing a neighborhood landmark is a tricky business, but at Fat’s you can eat well for $15, and co-owner Erika White instills an incredible sense of hospitality: promising signs of a new neighborhood institution.
