I was heading into the G concourse to catch a AE flight to CLE today and noticed some bright lights and greenery in the rotunda area at the head of the concourse. I wandered up the stairs and found that the Chicago Department of Aviation is sponsoring an "urban garden" above the G concourse. It's a small installation with bright lights and white pillars that have a variety of vegetables growing out of them. There was a gardener tending to watering the plants while I was sitting up there. There is quite a bit of space to relax, with lots of tables and plastic chairs surrounding the garden area. While I looked around and sat for about 45 min, there were only 4 other people up there. Definitely nicer than sitting at the crowded G gates. There are some posters and signage explaining the project, though honestly I'm not 100% of the accuracy of the information. If you read the text in the pic below carefully, you'll see why. Either way, I thought it was an interesting new addition to AA's T3 in ORD (looking forward to Tortas Frontera opening soon!), and also a quiet place to relax before a flight if you happen to not have AC access. Just go up the stairs in the rotunda at the front of concourse G.
