Purple Door serves good Coffee with a purpose. They are a non profit 501C3 that hires people that want to get a chance to change their lives from being from the street. That alone is worth the patronage. I met Madison the day I was there and you can immediately tell that she is friendly and approachable.
I did not get to geek out on my coffee with the barista there. But knowing she was new and not really much of a coffee fanatic did not deter my experience.
The place is not hard to find, and is decorated comfortably.
If in Denver – Go. This is a good place with a great cause.
