So yeah, thing to do now in Atlanta now is the Beltine. I'd get an Uber to Krog Street Market and walk up the Beltline trying out different places. If it's during the day Friday, Ladybird won't be too crowded. Some other options:
Krog Street - Get a beer from Hop City, and pick up a sandwich from Richard's
LadyBird - Get a Tropicalia and saddle up to the bar overlooking the Beltine
Victory Sandwich Bar - Have a Jack & Coke slushie and continue north
New Realm Brewing - new brewery by Stone's ex-master brewer right on the Beltline with an outdoor bar
9 Mile Station - Roof of PCM, has putt-putt, some games, a great view and a neat experience. If you aren't into walking, I'd just come straight here and day-drink on the roof. edit: looks like they don't open until 3 on Fridays, so depends on when you want to start drinking
Good luck.
