I'm the last one to defend a single story, suburban style restaurant in the core of our city, but I would not be upset if The Varsity was never redeveloped. Too much history and the place is uniquely Atlanta. The president even makes a trip there every time he comes into town.
That said, the adjacent surface parking lot and garage could absolutely be redeveloped. Provide parking in a new apartment or office building on the redeveloped lot and convert the parking in front, facing Spring, to outside patio seating or some sort of public space geared toward pedestrians and cyclists.
IF the entire place is ever redeveloped, I hope they at least recycle as much of the interior and exterior as possible to give it the same look and preserve its history. Also, can't get rid of the large V sign facing the connector.
