Underground Diner

Underground Diner puts a modern spin on the classic American diner in South Downtown Atlanta. The smash burger is the dish most mentioned by regulars, and it's earned a reputation as a standout on the menu. The room carries a lively, contemporary diner feel that shapes the experience as much as the food does, and service has built a following for being friendly and attentive — the kind that turns first-time visitors into repeat ones.
