Emerald City Coffee is located underneath the Sheridan Redline stop at 3938 North Sheridan Road. I went to meet up with a friend who lives in the area. I ordered a cup of their ginger peach tea and they offered me one bag or two.
I got one since I don’t like my tea too strong. Later I went up again and got a blueberry scone. 
The scone was very soft and pretty decent sized. The workers were pleasant and seemed to be enjoying themselves and the little cafe was pretty packed. There wasn’t a ton of space for a lot of seating and my chair kept hitting the persons behind me, but the cafe had a nice friendly atmosphere and my friend and I easily were able to sit and talk for a long time.
