I attended a festival here (the German Bierfest, which as a side note, was awesome!) and for sure I like the fact that more and more events are headed to the park.
It is very MARTA accessible for events, and I was able to find decent parking for five bucks on a weekend. It's pretty much a big green space, but if you live or work downtown, I'm sure that it's a nice refugee from your cube and a chance to roll your toes in the grass a bit.
Being very close to our infamous Underground, there can be some characters walking around. And you can buy a fake Coach bag around the perimeter of the park too. But the park overall is quite pleasant and a nice reprieve from the concrete and glass surrounding!
Also, according to the Atlanta Downtown's website, they have music every Wednesday in April, May, September and October during lunchtime!
