I had an Original Sin cider at Kuma's Corner in Chicago last week, it was nice.
Funny you should mention that as I was just looking at Kuma's menu online yesterday while planning my Chicago trip and saw that on there. I saw they also had Blackthorn Cider listed which I'm not a big fan of so will give Original Sin a try if you reckon it's good?
I enjoyed it, Kuma's was the best part of my last Chicago trip. Just get there early, we got there 30 minutes before they opened and there was already a line down the street. But the burger was amazing.
