I was so happy to find Intelligentsia coffee in Denver! Intelligentsia coffee is delicious and I'd always pop in to buy a bag when I was in Chicago. I recommend their pour-over coffee and Black Cat espresso.
The location is a little strange because there are hipsters working inside but it's located in the wealthy Cherry Creek area. There's metered street parking, so go on a Sunday and it's free! There's plenty of seating, and lots of seating outside as well.
