re: I come in peace. Looking for a good lunch spot in downtown ATL

S someone mentioned earlier West Midtown is gonna be your best bet and that includes Miller Union,JCT Kitchen,The Optimist.Marcel etc.All are pricey and pretentious but it's probably right up your SIL's alley.(Optimist would my choice but all are good)

You're right down the road from MCB and can Uber from all these places at a minimal cost.

Might wanna go and make a reservation now.
