Somehow I went through my otherwise-pretty-complete Mass Effect 3 playthrough without managing to run in to Kelly Chambers. I did import a save from Mass Effect 2 in which I'd saved her, so my understanding is that she should have been there for me to find.
I've seen this answer about how to romance her, but both the answer and the wiki it links just says she's "on the Citadel". Since I apparently completely managed to miss running into her, I'm wondering:
Where exactly on the Citadel is Kelly Chambers?
